Most people prefer it "Off" for gaming as it "seems to be the fastest." The "high" setting "seems to have the slowest response time, but it reduces ghosting." Going by this, Off would probably be the best for gaming and high would be more for watching videos or moving when you want better image quality, but settings in between could have a balance between the two. At that point it's down to your preference.
m playing CS:GO professionally, and would like to achieve the lowest Input lag/latency possible, im using csgo ingame frame rate limiter set at FPS_MAX 300, but recently i heard that in Nvidia profile inspector, frame rate limiter mode changing from default to "Limiter force off v2" or other options reduces input lag in game significally. I would like to ask witch one shoud i use for lowest input lag in game or do frame rate limiter mode impact anything at all when changing it if Frame rate limiter set to off:?
