Windows 7: V-Sync locks at 55hz/fps instead of 60 on Windows 7

06 Nov 2009   #1

Windows 7 Home Premium 64-bit
V-Sync locks at 55hz/fps instead of 60 on Windows 7

While applying Vsync on games, be that through D3D Overrider or the in-game options, or double buffered or triple buffered my framerate is locked at 55.4 instead of 60.

I have Win 7 Home Premium x64 and before that Vista Ultimate x64 and didn't have this problem on Vista. I have tested on my monitor (Dell 2208WFP) and my Pioneer 4280 plasma and it happens in both.

My card is a Sapphire Radeon 4850HD (on Catalyst 9.10 drivers) and on the CCC it's registering the refresh rate as 60hz. So I haven't got a clue what is going on.

P.S. Also have this weird stuttering on Grid (steam version) where the game just sort of freezes for a half a second, this also didn't happen on Vista.
