gsync question help

[roro13200]

Hello, as the title suggests, I have a few questions.

sorry in advance if my questions seem strange to you but I don't have too much knowledge


first of all, i have a little strange feeling with gsync, at the beginning of my gaming session when i start the computer, i have a certain inputlag, and the more i advance in my session, i feel that the 'inputlag is reduced, I would like to know if possible the cause of this?

when I play with gsync, the colors of my screen change, that again is not very serious, on the other hand the light impact is more intense, and hurts my eyes, I tried various settings on my screen, but without success, Do you have a track to tell me, so that I can settle this little problem?

I play games that are capped at 60FPS and that integrate their own vsync, I play on a 240hz screen, and I remove the vsync (ini file of the game), or not, I don't feel any difference, I wanted to know if it's 'is normal ?

last point, concerning the scaling of the desktop, should we let the gpu manage this or the screen?
moreover, if you play games in 1920/1080p, should you simply not put any scaling in the nvcp?


sorry for all my questions and my very poor english!

Thank you !
