This ini tweak along with other tweaks will help you fully utilize your GPU if your CPU is bottlenecked while also improving FPS substantially.

Requirements:
Cyberpunk 2077 1.05 or later

Benchmark test specs:
i7-3770 4 cores 8 threads 3.4Ghz
12GB DDR3 1600Mhz
ASUS dual GTX 1060 6GB (461.40 driver)
1080p 60hz

Benchmark Results: (Used Fraps)
(Ultra + ini tweaks, Config Overhaul and NVIDIA Control Panel tweaks @ 1600 x 900 Resolution)
2021-02-14 20:08:25 - Cyberpunk2077
Frames: 12074 - Time: 241141ms - Avg: 50.070 - Min: 38 - Max: 70

Benchmark Notes:
I closed Discord, Chrome and other CPU heavy applications that might skew the results.

Installation:
Please change FloodMinNonLoadingThreads to 1 number lower than your total threads on your CPU. for example 4 cores = 8 threads (put 7 instead), 6 cores = 12 threads (put 11 instead) (You get the idea, threads is equal to double number of cores in your CPU)
Copy the generalOptimization.ini file from the generalOptimization.rar and place it in:
..\Cyberpunk 2077\engine\config\platform\pc

Uninstall process:
Delete the files, and you might need to verify game files because deleting does not revert *.ini tweak setting files then start up game to apply changes.

Tweaks:
Use Config Overhaul for Cyberpunk 2077 and click on the Optimized option then close the app.

for NVIDIA Graphics Cards' user, use NVIDIA Control Panel:
Go onto the desktop, right click > NVIDIA Control Panel > Manage 3D settings > switch from Global Settings to Program Settings (use Global if you want other games to adopt the tweaked settings) and under "1. Select a program to customize:", find cyberpunk2077.exe and redlauncher.exe, if it's not there, click "Add" and and click browse if the game doesn't appear under the "Add" pop-up window.
These are the settings to change:
Set these
"Antialiasing - Mode" to "Enhance the application setting"
"Antialiasing - Setting" to "4x"
"Antialiasing - Transparency" to "Multisample"
"CUDA - GPUs" to "Use these GPUs" to your dedicated graphics card (reason being some games use integrated graphics if available instead of dedicated to run which makes the game lag)
"Multi-Frame Sampled AA (MFAA)" to "On"
"Shader Cache" to "On"
"Texture flitering - Anisotropic sample optimization" to "On"
"Texture flitering - Negative LOD bias" to "Allow"
"Texture flitering - Quality" to "High performance"
"Texture flitering - Trilinear optimization" to "On"
"Threaded optimization" to "On"
And hit "Apply".

Notes:
Use this in conjunction with NVIDIA Control Panel to give more fps for GPUs like GTX 1060 6GB or similar. If you are a AMD graphics user, I am currently investigating if users have a similar functionality that allows to tweak Anti-Aliasing, Texture Filtering, etc.
If you are GPU bound, it is highly advisable to switch to lower resolution like 1768 x 992 or 1600 x 900. This lets you push a bit more fps when not CPU bound. (or not if you want crisp quality)
