Developer Settings Mod for Cyberpunk 2077 (Config Overhaul)

You can tweak developer settings with the Config Overhaul Mod. If your PC is struggling to get high FPS, you should use this mod.

It works by generating configuration files, and will not modify the game executable. So new Patches will still work with this Tool.
You can pick out of 4 Presets, or just play around with the custom settings.

Note: Disabling “Async compute” will only increase FPS on older graphics cards. (All Pre-RTX 20xx Series GPUs, All pre-Vega Radeon GPUs with the exception of the RX590, that has a newer manufacturing process and improvements on Architecture level)
Disabling Async compute on newer cards will lower the FPS. But try both out just to be sure.
Also it does not degrade the image quality so you are save to try it.

Disable Async compute ~ 2-5 fps more (Some older Nvidia GPUs can even get up to 25 FPS!)
Optimized Preset ~ 5-10 fps more
Low ~ 10-20 fps more
Very Low ~ 14-24 fps more

Presets were made with an AMD RADEON RX480 GPU.

I recommend to try out the Low preset first. If you got a beefier GPU, go for the Optimized Preset.
Use the Very Low preset only when you really need, because it makes the game ugly.

The tool will apply the new config, when you close it.
