Hi,

i have a question about 3d software and special drivers.
Im working on a GL application and it behaves differently
sometimes depending on the driver versions (buggy). Is there
a way to install a software with a pack of drivers (NV/ATI)
that the application uses only? Put certain dlls into the current directory? I know you have to install
drivers and reboot and so on, but still im wondering if
there is a way.

Thanks.

First - I wouldn't install an application that installs graphics drivers. What it I want another application that installs different driver version? Chaos. Not to mention I just downloaded new drivers myself.
Second, most differences caused by driver change are caused by bugs in the application itself.

I recently discovered, that my game produces some bad pixels. It turned out that I had an uninitialized variable in my fragment shader, but older drivers accidentally made my shader work properly.

You can try Mesa3D software rendering if bad drivers really are the source of the problem: http://www.mesa3d.org/ .

On Windows you can also drop opengl32.dll in the application executable directory, but it will not support anything newer than GL1.1.
