Hi there, the title is a bit silly but hopefully someone can help me out with this. In the present and previous drivers (388.13, 388.31 and 388.43) I've been experiencing odd behaviour: whenever I enable vsync, be it through the control panel or in-game, the drivers impose a framerate cap of (Refresh Rate) - 2. This even happens when using fastsync. This is not the usual when enabling vsync. Yes, I've made sure RTSS is not doing the cap nor has the driver such option enabled. I've tested it with both 60hz and 75hz refresh rates and both get capped at 58fps and 73fps respectively. Now, I am aware of the whole reduction of input lag when you cap 2 frames below the refresh rate, but I find the frame skipping unbearable and I've been previously using the method posted here by RealNC to great success and wish to continue to do so. Is anyone else experiencing this? Is this some new feature nvidia implemented in the drivers recently? Maybe some variable that enabled such behaviour? OS: Windows 7 x64 Pro. tl;dr: whenever I enable vsync, be it in-game or through the control panel/inspector, out of nowhere, framerate is capped at 2 frames below refresh rate (58 fps if i use 60hz, 73 fps if i use 75hz). I am NOT using any software to cap the framerate. Cheers! edit: issue resolved, occam's razor: dust in the hdmi contacts in the GPU port and/or not securely plugged in cable, really stupid shite but to great effect. Hopefully this will save some hours to some poor soul in the internet with a similar problem.
