Here is a simple way for you to optimize your system for DCS based on the GPU you have. We will go through the settings for RTX 3060 TI, RTX 3080, RTX 4060 TI, and RTX 4090. In cases you have a different GPU you can probably interpolate between two of these settings to get your base optimized setting from where you can further tweak.
A great VR experience has always been subjective, however, most people find that for DCS 60 to 90 frames per second works well. This setting guide aims to keep the frame rate within these ranges while not reducing the overall resolution of your Crystal Light.
Note: We assume that your CPU and RAM are roughly in league with your GPU and that you're not running a fifth-generation i3 along with a 4090 GPU and 8 GB of RAM for example
Step 1.
Go into the Nvidia control panel, and under 3D settings ensure that Image Sharpening (if you have it) is set to 0.25. You will find that this setting improves the clarity of very distant objects dramatically.
Step 2.
Go to Pimax Play and set Refresh Rate to 72 Hertz.
Leave render resolution, etc. on maximum.
Step 3.
Step 4.
