What is the best way to test graphics and visual effects in games?

To test graphics and visual effects in games, use mockups for static representations, style exploration, and early feedback. Develop interactive prototypes for dynamic testing, assessing user experience, performance, and iterative refinement. Conduct user testing to gather player feedback, observe interactions, and compare visuals with industry benchmarks. This comprehensive approach ensures a polished and engaging visual experience in game development.

Mockups solidate your ideas, helps you get feedback from your team mates. Concepting the art you are planning to do; I'd say that's the half way of all the creation. Also prototyping can help you understand the up-coming problems and solve them before hand. Such as seeing the issues with the scaling, lightning etc. So I'd order the steps as in below; 1- Ideation, imagination part. 2- Concepting the Idea 3- Prototyping it to see things clearly Especially in VFX and SFX prototyping the work you have done might also help with benchmarking, not only with the hardware and your code, but with the "feeling benchmark" to see if it delivers!

"Start simple" Creating mockups and prototypes to test essential game mechanics is required when designing a simple level with basic graphics. Developers can run the prototype to evaluate functionality and identify potential changes by implementing a limited environment and placeholders for crucial features. This early stage permits incremental improvement before to investing on elaborate graphics, resulting in a more efficient and focused game development process.

Again, prototyping is the best and most optimised way to implement graphics testing in game development. Or generally speaking, any kind of pre-production testing and verification. It is clear that prototype testing is an advantageous development strategy versus direct implementation in running projects. The investment/risk ratio is favourable due to the minimal costs and the possibility of iterations before moving to the production stages of the product. Obviously there is always a cost involved but in these stages they are minimal compared to the direct production stage of the game.

When it comes to testing graphics and visual effects in games, it's crucial to strike a balance between technical proficiency and artistic vision. 1?? Collaborate with beta testers: Passionate gamers who can provide valuable feedback on the visual aspects of your game. 2?? Conduct extensive playtesting: Create a dedicated team to thoroughly playtest your game across various platforms and hardware configurations. 3?? Leverage industry-standard tools: These tools enable you to analyze graphics performance, optimize visual effects, and achieve stunning visuals. 4?? Seek feedback from the gaming community: Their insights and suggestions can provide valuable guidance on improving the graphics and visual effects in your game.

Simplify shader designs to improve efficiency, employ LODs for scalability, and reduce unnecessary computations. Balance quality and performance using texture modifications for materials, use shader features carefully, and test periodically on different hardware for compatibility and best performance across platforms.

I highly recommend getting used to analyse graphics workloads using a graphics debugger like RenderDocand understand the graphics pipeline as this highly influences the results of your shaders and the performance. Also, study HW specifics of your target platform and understand strengths and weaknesses and how to optimize for it.

Enhancing visuals through shader manipulation. In a sci-fi space exploration game, experimenting with shaders and materials transformed the appearance of spaceship surfaces. Adjusting shaders for metallic textures and applying reflection effects significantly elevated the realism of spacecraft models, enhancing the overall immersion for players.

Know your target platform first: how many draw calls you can have, how much textures you can use .Try to make an "effects contructor" : check what you'll need in terms of materials and shaders (in the most cases ) and cover 90% of your effects by reusing it. Merge textures in atlases, reduce materials count , use profiler to check materials switches / batches count.

When dealing with shaders and materials consider: 1) Performance and Geometry Budget: Efficient shaders are essential, following a pre-set geometry budget tailored for the specific target platform. 2) Target Style and Visual Balance: Achieving a balance between artistic goals and technical constraints, whether for lifelike graphics or a specific style. 3) Adaptability and Flexibility: Shaders and materials should be adaptable for different environments and lighting conditions, ensuring consistent quality across varied game scenes.

Use post-processing effects to enhance graphics, but use them wisely for performance. For artistic impact, prioritize aspects like depth of field and bloom, and consider enhancing with appropriate settings. Test effects across hardware on a regular basis to ensure consistent and pleasing results.

The use of a post-processing stack or post-processing volume is standard practice in modern game development. It allows developers to have more refined control over how these effects are applied, adjust their intensity and combine them effectively to achieve the desired result. This flexibility is vital, as different scenes or types of games may require a unique approach to the application of these effects. However, it is crucial to find the right balance between visual quality and game performance, especially considering the variety of hardware on which players might run the game.

Post-Processing Effects has pros and cons and one crucial point to evaluate is why you need such effect. Sometimes the chase for realism or enhanced effects could lead to a product with performance issues. So keep in mind that adding post-processing effects will require more effort to make sure that they are performing well.

Post Processing (PP for short) effects should be used to modify the final image of the game. By that I mean how the frames are rendered to the player. PP contains a lot of effects that you can play with depending on the engine version, in Unity for instance, you get to choose from film grain which adds noise, to tone mapping which allows your to give you game a more dramatic color specially useful when dealing with HDR. Play around with PP until you find what you think best suits your game.

Adding depth and ambiance through post-processing. Implementing post-processing effects was vital in a survival horror game. Applying effects like vignette and desaturation heightened the game's suspenseful atmosphere, intensifying the feeling of dread in ominous environments. give an a practical example well detailed

While tools like profilers and debuggers provide valuable data, don't solely rely on benchmarks. Playtest your game actively, observing visuals and performance across different hardware configurations and gameplay scenarios. This human-in-the-loop approach helps identify subtle issues and ensure a satisfying experience for real players.

I am a supporter of continuous optimization and testing throughout development. Try to test small implementations individually and see how they affect performance. This will save you time when you obsessively try to find the bottleneck in performance.

Texture Optimization: Downsizing textures using efficient compression or smaller-sized textures maintains visual quality while reducing memory usage, benefiting performance on lower-end devices. Level of Detail (LOD) Techniques: Dynamically adjusting object details based on distance conserves resources. Simplified models for distant objects enhance performance without compromising visual quality. Shader Simplification: Streamlining complex shaders by minimizing instructions or removing unnecessary effects maintains visual appeal while improving performance efficiency.

Creating models and prototypes and having well defined at a conceptual level the graphic style that is required, also a very important part is the feedback from 3rd parties, to avoid getting burned with the project.

Drawcalls and shadowcasters are at the core of performance for RT3D, even more critical than object polycount. The better the assets are conceived the best performances you will get: - Minimize the number of materials per mesh, - Merge as many meshes as possible and delete hidden faces, - Review small objects shadowcasters, - Count with old tricks such as normal mapping instead of higher polycount, or cutout shaders instead of detailing fence etc. - Consider early what objects should be separated from each other, - and last, a good optimization is to bake light on static meshes, (they can be also merged on the fly by most of the engines, called "batching") as to get better performances as well as better visual quality.

For profiling, Game Engines usually have their own in-engine profiling solutions. However, I suggest you go directly to the vendor specific tools as these can usually provide way more platform-specific information and tips than what can be collected at runtime by these engines. For debugging GPU workloads, RenderDoc has become a standard. However, Consoles proprietary debuggers tend to be really good too.

In my experience to test graphics and visual effects in games effectively, using a mix of automated tools for performance analysis and manual testing by experienced QA testers. Automated tools help identify performance issues, while manual testing ensures a thorough evaluation of visual elements. Gathering feedback from a diverse group of players also provides valuable insights into subjective aspects of graphics and effects.

Game development is all about testing and testing again. During the planning phase is important to decide not only which effects will be present in the final product but also how to test them. A good tool could improve the quality of the game, however a bad tool could generate false positives and prevent the team from seeing important aspects that could be fixed before any big delivery. Consider start the development choosing which tool you will have on your side for that.

A very practical way to identify bottlenecks is to look at the behavior of the frames per second (fps). Generally the FPS is reduced in scenes with a large number of simultaneous objects, complex shaders, physics simulations or some error that affects performance. You can generate a log to save the FPS over time or displaying the value on the screen. If you are testing the game on the macOS operating system and it uses the Metal API, you can run the following command in a terminal: "defaults write -g MetalForceHudEnabled -bool YES" before running your game or the game engine editor. This will display the current, lowest and highest FPS information, as well as other useful information. To hide it, use the same command changing YES to NO.

Involve cross-platform(if possible) closed or open betas for your developing product. To achieve more stable mechanics and working visuals, listen to your carefully founded crowd previously. And most importantly, play-testing your own product is crucial for to eliminate any small details/mistakes if developers or designers missed out on.

When evaluating feedback for game visual, it's important to keep in mind that, a user's negative feedback on a visual of a specific area or item in your game does not necessarily mean it doesn't look good, but rather the current visual is not properly communicating with the player during gameplay. It's more important to make sure the visual is complementing the gameplay experience than to just look pretty.

Iteratively refining visuals based on feedback. Player feedback is pivotal. In an action-adventure game, adjusting lighting effects based on player testing enhanced gameplay immersion. Tweaking ambient lighting and shadow intensity heightened the game's visual dynamics, enriching the overall experience.

The developed game needs to undergo testing sessions at various points in the development stage, especially in the final stages. These tests help identify different levels of bugs, as well as requested features that can significantly enhance the game. There are various ways to conduct these tests, and a simple method is to enlist individuals to play the game and then respond to a survey with both closed and open-ended questions. Oh! These feature requests must be carefully analyzed so as not to extend the game development timeline too much or deviate the game from its purpose.

Oh dear, this is the part that will take your time mostly I'd say. Feedback, never ending iterations... One of the publishing managers I worked with once told me "You see Cemre? The game gets better with each feedback and iteration! We should keep doing this!" I can confirm, it always gets better with each iteration, but we should always concider the time we are spending in game development. It has to be cost effiecent. Besides that, I've learned that the most honest reviews for your games always come from refund notes. Always read those angry long paragraphs. They are the people expected something special and dissapointed for some reason. And game testers ofcourse. Test your game as much as possible, with festivals, open demos etc.

Always leave a open door for your testers/players. Let them to be involved in your product. Convenient way to that could be a big "Feedback" and a "Bug Report" button. Since the players are the audience, their opinions do matter for the best execution of the finised product.

Make sure to use appropriate effects for appropriate hardware! You can't use ray tracing if you are targeting mobile platform, sure it will run on some phones, but wouldn't be a nice experience for others. Before adding any effects to your game, make sure to always check what is the target platform.

It's important to consider the performance impact of the visual effects. If it's significant enough to have an effect on your game's framerate and it's not essential to gameplay, then it's worth adding a setting to allow player's the option to disable it. However, if your game relies on it, remember that this higher performance demand could mean that you will be excluding people who lack the proper hardware from your target demographic. Look for ways to optimise the effect, or even using newer techniques like DLSS to make up for the performance knock. But always weigh the pros and cons, if an effect is barely noticeable but requires a lot of performance (like ray tracing in some titles) then it might be worth removing.

We developers always have to find the best compromise between graphics quality and performance, but as the hardware evolves, it always brings more power to the user and more features to add for the devs. For years I have been developing on lower hardware, so if it runs smooth on my years old pc the experience will be fine for most of users! And so it demands the same dedication to optimized meshes and textures, whereas today powerful GPUs push to add more objects / Fx / posteffects without being careful on basic optimizations. Looking toward future without ignoring where RT3D comes from!

It's all about adding "Juice" to your game. If your graphics are running smooth, and you can trigger those excellent "juice" effects quickly to give the proper feedback to players, you are winning. Things such as camera shake, particles, and camera movement, are just a few key examples of what takes the Game Feel to a new level. For more check out: https://www.youtube.com/watch?v=216_5nu4aVQ

Narrowing your project to specific platforms / hardware is the easiest way to guarantee performance and compatibility. This can be a helpful trick for new or solo developers. This is why I love developing VR games. It is an expectation that VR games run on specific hardware (Quest or laptops with RTX graphics cards). So if I choose the Quest 2 as my platform and see no performance issues, I have some safety in knowing that this will be the case for the majority of users.
