Lost v-sync with Windows 7

[Les]

Hey all, didn't want to resort to begging, but I just can't get v-sync enabled in 1946 with Windows 7 Ultimate 64-bit, except in windowed mode, and was wondering if anyone knew of a fix.

I'm using the same nVidia drivers and user config that worked successfully with Vista Ultimate 64-bit. Have got v-sync forced on in global settings and the 1946 profile. Triple buffering's off in both. I can enable v-sync in DirectX mode, but then of course I lose all the OpenGL effects, which is worse than running in windowed mode.

Using nHancer and RivaTuner to over-ride the nVidia control panel hasn't helped. I must have tried almost every possible combination of control panel settings but the screen tearing persists.

Have re-installed using compatibility modes, from 4.07 clean off the DVD up to 4.09 and back again. Tried the latest nVidia drivers, but am currently using the 182.50 drivers that worked before, for compatibility with other programs. Had a look around the web but obviously haven't found any solutions that worked.

Anyone else getting the same thing or have any suggestions?

I'm running ATI and I'm having the exact same problem. It's only happening with IL2. Strange. It's odd that a simple upgrade from Vista to 7 could cause this problem in only this game. :confused:

Yeah, in my searching I've seen at least as many ATI users as nVidia users having problems. I don't know what to make of it. The fact that Microsoft is behind Windows and DirectX, and that DirectX and OpenGL are sort of competing, makes me suspicious about Windows' treatment and support of OpenGL programs. But, who knows.

Likewise with Win 7 64-bit I have no issues with applying Vertical Refresh (Ati-speak for v-synch) in the software and it working with IL-2. In OpenGL in Perfect mode. Could this be a UAC issue that prevents alterations to the software? I have UAC dialled right down to prevent it from blocking my adjustments.

Just incase anyone else has this v-synch problem in the future and does a search of these forums, the latest nVidia drivers 195.62 have fixed the problem for me. Did a test changing back and forth between the new drivers and the old and it was definitely some internal change within the drivers causing the issue, in conjunction with Windows 7.

V-Sync on Windows 7 is back and working with the new release official nVidia drivers

it wasn't only il2 which previously suffered but also DCS Blackshark

I've can't get v-sync to work when 1946 runs in opengl mode.

I have windows 8 x64 and HD6990m (CCC 13.2 beta 5)

Any ideas? Anyone have it working in Windows 8 x64 with similar ATI card?

I've just tried it and it works for me. I forced ON v-sync (I thought) with CCC, closed CCC and started game, no V-sync. I closed game, opened CCC and v-sync was OFF, I forced it ON, applied it (for sure) and started game with CCC open. v-sync was ON. I was sure I applied setting first run through and if I did I don't know if leaving CCC open made any difference. Now back to normal with v-sync OFF.

I have an HD7970 with 13.2 Beta 5 driver on Win7 64 and game in opengl.

I have an HD7970 with 13.2 Beta 5 driver on Win7 64 and game in opengl.

Might be a Windows 8 anomaly then.

With my ATI card it helped to install ati tray tools, vsync is only working since then. I have read the same somewhere else.
