Working V-Sync on the ATI 5870 in Vista

Recommended Posts

I just managed to get V-Sync to work reliably on my ATI (Gigabyte) 5870, on Vista 64 with the Catalyst 10.2 drivers.The trick was to use ATI Tray Tools (V1.6.9.1472, from www.guru3d.com) to build a profile for FSX, and then run FSX from the ATT dropdown menu. In the Direct3D Tweaks tab, check "Force VSync (Vista Workaround) box and UNcheck the "Force to use triple buffers" box. FWIW, the other settings in the profile I use are:Anti-Aliasing: 4X/Wide-tentAdaptive AA checkedSS Mode: QualityMS Mode: 2AF: Quality with Trilinear/16XEnable High Quality AF is checkedTexture Preference: High QualityMipMap Detail level: High QualityWait for Vertical Sync: Always OnCatalyst AI: highSupport DXT and Bump mapping both checkedGeometry Instancing: checkedIt seems that with the Force VSync workaround enabled in ATT, there is much less tearing also in windowed mode, although there is some. Also, anytime a 2D window is opened/closed when using this setting, the screen flashes. For someone flying in a VC most of the time, it's probably a good way to go. For people like me that use 2D still, the flashing every time you open/close a subpanel may be more annoying than the tearing with VSync off.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

These are good news. Maybe it is the new Version of ATT but it's the first time I got VSYNC in Windows 7 64-Bit with my 4850. However, I don't think I will be able to use this as it does not work with FPS Limiter, as it will only allow .exe files (fsx.exe) for profiles. Any ideas?

There's a nice freeware utility that'll convert a .bat file to an exe file at: http://www.fyxm.net/batch-to-exe-75643.htmlThat said, I doubt that the ATT VSync tweak will work in conjunction with the FPL renderer hook.CheersBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO
