Settings in games that makes your GPU choke

Beside resolution and refresh rate, which is obvious, there are multiple settings going heavy on gpu usage.

The most GPU-demanding settings in games are typically related to shadows, lighting, and reflections. Here are some of the settings that can have a significant impact on your GPU’s performance:

1. Shadow and Lighting Quality: Shadows and lighting are among the most demanding tasks for your graphics card. They may appear as separate settings, but they work together.
2. Reflections and Ray Tracing: Reflections can be quite demanding on your GPU, especially when ray tracing is involved.
3. Anti-aliasing: This setting helps to smooth out jagged edges but can be quite demanding on your GPU1.
4. Per-Object Motion Blur: This setting is demanding on hardware, but it looks much more natural.

Remember, the impact of these settings can vary depending on the specific game and your hardware. It’s always a good idea to experiment with these settings to find the best balance between visual quality and performance for your specific setup.

In 4K resolution, the most demanding post-processing settings in games are typically related to reflections, shadows, and lighting. Here are some of the settings that can have a significant impact on your GPU’s performance:

1. Shadow and Lighting Quality: Shadows and lighting are among the most demanding tasks for your graphics card. They may appear as separate settings, but they work together. Turning down your shadow and lighting quality will improve your performance - i always make shadows medium or even low, try comparing in game real time if they impact much of gameplay and performance.
2. Reflections and Ray Tracing: Reflections can be quite demanding on your GPU, especially when ray tracing is involved - depending on your game and settings its advised to turn it off or on, theres no one rule.
3. Anti-aliasing: This setting helps to smooth out jagged edges but can be quite demanding on your GPU - while playing on 4k totally useless.
4. Per-Object Motion Blur: This setting is demanding on hardware, but it looks much more natural - also can be bad for eyes so i advise to turn it off or make it lowest possible to avoid screen smearing.
5. Screen Space Reflections (SSR): This allows for the reflections of objects to be shown in real-time.
6. Screen Space Ambient Occlusion (SSAO): This determines how much ambient lighting an object is exposed to - since i play on 58'' 4k i turn this setting off.
7. Depth of Field (DoF): This simulates distance by blurring far away scenery.

Remember, the impact of these settings can vary depending on the specific game and your hardware. It’s always a good idea to experiment with these settings to find the best balance between visual quality and performance for your specific setup.

Ambient Occlusion (AO): This is a shading and rendering technique used in 3D computer graphics, modeling, and animation. It calculates how exposed each point in a scene is to ambient lighting, and simulates how objects block light from each other in a given environment. AO helps to add a sense of depth and realism to the final image by creating shadows where objects intersect or are close to each other. However, it can be demanding on your GPU. Turning AO down or off can increase your performance, especially in some games.

Tessellation: In computer graphics, tessellation involves dividing datasets of polygons (sometimes called vertex sets) that present objects in a scene into suitable structures for rendering. Especially for real-time rendering, data is tessellated into triangles. Tessellation can save memory and bandwidth but at the cost of GPU performance. It can be beneficial for reducing memory bandwidth for animated or multi-instance objects in the scene. However, turning tessellation off can help with stable performance.

In terms of 4K gaming, both Ambient Occlusion and Tessellation can have a significant impact on your GPU’s performance. They can enhance the visual quality of the game, but they also demand more from your GPU. If you’re experiencing performance issues, you might consider adjusting these settings. However, the impact can vary depending on the specific game and your hardware. It’s always a good idea to experiment with these settings to find the best balance between visual quality and performance for your specific setup. Remember, the goal is to achieve a smooth and enjoyable gaming experience. If turning these settings down or off achieves that without noticeably impacting the visual quality, then it could be worth it.

Next is closer look at post processings, which most players blindly turn on:

let’s compare these anti-aliasing techniques:

1. SSAA (Supersampling Antialiasing): This technique generates the game’s image at a higher resolution, then scales it down to the screen size, resulting in excellent edge smoothing effects. However, it heavily burdens the graphics system. Without a high-end graphics card, you might experience choppy gameplay instead of smooth object movements.

2. MSAA (Multisample Antialiasing): MSAA operates similarly to SSAA by using downscaling, but it only scales pixels located at the edges of objects. This method relieves some of the load on the graphics processor. It’s a significant improvement over SSAA in terms of performance.

3. FXAA (Fast Approximate Anti-Aliasing): FXAA improves image quality by reducing jagged edges. It’s a post-processing method, meaning it applies after the image has been rendered. While it doesn’t provide as high-quality output as other methods, it has a minimal performance impact.

4. TAA (Temporal Anti-Aliasing): TAA is considered the best option for quality, ghosting reduction, and handling of temporal aliasing caused by camera movement. It’s a newer shader-based technique that has become the norm.

When it comes to 4K gaming, the need for anti-aliasing depends on various factors. On a 27" 4K monitor, for instance, the image is so crisp and sharp that you likely won’t even need any sort of AA. However, some players still prefer to use AA at 4K for certain forms of transparency and to stop pixel shimmering.

If you have a high-end computer, SSAA might be the best solution. For mid-range PCs, FXAA might offer the most frames per second. AMD’s FidelityFX Super Resolution (FSR) 1.0 is beneficial at high resolutions like 4K UHD when using the ‘Ultra Quality’ or ‘Quality’ presets.

Ultimately, the best way to figure out which type of AA works best for you is to try each one and find the sweet spot between image enhancement and a tolerable performance hit.

This is just a small portion of settings tips to set in games, remember it best to go slowly from low settings to higher and check multiple times how much they impact game. Hope it will help you in setting your favourite games.
