Every game is like every human being, with unique characteristics and unique problems.
Different operating systems will have different problems, and different drivers will also cause different problems.
Here I report two unique problems to you, and by the way, I will discuss the negative optimization of the NVIDIA driver.
I noticed that in the Panzer Killer game, although my experience tells me, this is a game with relatively poor compatibility, it is best to run it on windowXP and the old version of the driver.
But later proved me wrong. In windows7, using the 270.61 driver, you can run 300FPS, and the resolution can be selected to 1280*960*32.
In windowsXP, using the 270.61 driver (same as above), it can only run to 64FPS. There is a strange thing that locks its frame rate, even though I forcibly turn off the vertical synchronization. Even more strange is that the resolution can only be set to 1024*768*32, and there is no setting about 1280*960*32. If I manually modify the INI file to force the setting to 1280*960*32, the game fails to start directly, and Tell me he cannot render 1280 resolution.
I was not convinced by this result and downloaded the 177.35 and 337.88 drivers, but the result became exactly the same in the end.
In this experiment, win7 defeated winxp, which is incredible, but why?
---------------------
The second game is IGI2, a very famous stealth game.
In windowsXP, using my GTX280 and turning off the vertical synchronization, it can run to 144FPS, but there is a strange thing that limits its frame rate.
I switched back to windows7 and used the same version of the driver, and the game actually ran to 230FPS.
Oh, no no no no no no no no, here again and again.
Can someone explain?
