Thanks ab1225 for pointing me to this little app.
It is widely known, that Windows 2k and Windows XP are incapable of determining and setting optimal refresh rates in OpenGL and Direct3D applications. In some games (for example Q3-based games an Serious Sam (FE/SE)) user may force optimal refresh rate by means of game settings. But the number of such "smart"games is rather small. Most of the games under Windows 2000/XP leave user no choice besides default 60Hz (or 75hz). Of course, 60Hz is not the best mode to play or work.
Main function of this program is to solve this problem by letting user specify optimal refresh rates under Windows 2000 and XP for OpenGL and Direct3D modes. User may specify 1 refresh rate for 1 resolution.
Supported videocards:
· ATI RAGE 128/RAGE 128 PRO
· RADEON (including LE, VE, 7500, 8500).
Version 0.70 or newer let u manage other undocumented registry keys to improve performance and picture quality like force anisotropic filtering in Direct3D and so on. (Note: anisotropic filtering in Direct3D is supported only with drivers with version 6006 (2K/XP), 9008 (98/ME) or newer and only for Radeon 8500).
