I bought a 6600 video card, the first time I used FPS in PUBG it was at high settings
in the region of 100-120, then I selected the Antilag function in the AMD software settings,
after which the screen began to show 1980-1080 (I use a Samsung TV 40 'and I'm comfortable with 1680- 1050).
After that, I returned the resolution back to 1680-1050 and some kind of horror began,
the FPS in PUBG at any settings is no more than 60. In other games, the FPS also dropped, but not so much.
On the example of PUBG, maybe someone understands why the FPS was locked at 60 with any graphics settings.
Tried rolling back drivers, didn't help.
