Hey i am using a Ati Radeon 7000 64MB PCI And i was wondering was it ok or a good idea to change some of the settings in the control panel / direct 3d options and open GL options or leave them at DEFAULT ? ALso, is it ok to change the Refresh rate to sa 85HZ or 60HZ or leave it on default, which is: OPTIMAL????? And my last question, does ATI Radeon 7000 support DirectX 9.C ? I ask this because i notice when playing GTA III, like the first time you install , and when you run the game it checks your video card and see what is the best settings can be use when playing. Only thing, when going back into the DXDIAG thing , my DDI VERSION goes back to 7, when it was at 9 before running GTA III. Thanks.
