Cannot change the ingame resolution in Far Cry 4
Hello. I just bought Far Cry 4 from steam. Playing the game i got 16 FPS with my NVIDIA GeForce GT 640 on 1080 res. I therefore changed it to 720p. To improve my framrate a bit, i installed the newest driver for my card. It changed nothing concerning the FPS, but now i only have the option for 1080p in game, and i cannot change it down to 720 as i did before i downloaded the new driver.
I contacted NVIDIA live support and they could not troubleshoot this problem. I tried uninstalling and reinstalling the drivers but non of it works. When I un installed the drivers the 720p option game back, but when I was in the game, it went very blurry for most of the time. Please help
