Best sweet-spot settings for performance and quality in Unreal?

rmx

first i want to make color looks exactly same as the original texture
but even using unlit material, it never looks same color as same as unlit-view mode

and i know my computer can handle this animation in 60 fps,
but in unreal simulation, it barely run in 30fps

i believe some sweet-spot of settings i'm looking for
project settings, post-process settings or what,
i don't need other fancy ultra-realistic unreal features
only reason using unreal is blueprint
all i want about graphic is 2D-clean graphic

To achieve a balance between performance and quality in Unreal Engine for 2D graphics, you can follow these steps:

Unlit Material: Ensure that your materials are set to unlit to maintain the original texture colors. However, if the colors still don't match, check the color space settings and ensure that there is no color correction or post-processing affecting the output. You can refer to the discussion on setting unlit mode in packaged games here.
Texture Filtering: Adjust the texture filtering settings to ensure clarity. Use bilinear or trilinear filtering for smoother results, and consider enabling mipmapping to improve performance when textures are scaled down. More details on texture properties can be found here.
Post-Processing: Disable any unnecessary post-processing effects that might be enabled by default, as these can affect both color accuracy and performance.
Performance Settings: Optimize your project settings by reducing the resolution of textures and limiting the use of high-quality shaders. Ensure that your project is not using any unnecessary high-end features that could impact performance.
Blueprint Optimization: Since you are using Unreal for its Blueprint system, ensure that your Blueprints are optimized and not causing any performance bottlenecks.

By focusing on these areas, you should be able to achieve a clean 2D graphic look while maintaining good performance.
