1. The main problem is the inability to turn off motion blur 2. No FOV adjustment 3. The camera does not bounce at all when walking, so there is a feeling that you are floating in the air 4.There is no frame limit (I usually play without frame synchronization, and set the lock to 60 fps) 5. It is impossible to remove the crosshair 6. After exiting / entering the game, the "take" and "inspect" keys are reset And I would like a slightly better performance....
