View Full Version : Quick Driver Question

09-03-04, 06:53 PM
Hi All,

I asked on another forum, but I always like to be doubly sure.

I currently right now run Windows XP SP2 (with DirectX 9.0c) and I run the latest nvidia drivers 61.77. The drivers work great in all my games, except Morrowind. So what I'm wondering is this.

If I were to downgrade to 61.76 would they work with DirectX 9.0c? Would I notice any problems doing that? Any help would be great :)

Thanks in advance,

yes, directx 9.0c would work with the 61.76, but then u won't have sm3 support, which is only available in 61.77 and higher.

SM 3.0 support is in all 6x.xx drivers it's just that 61.77 finally added it to the INF, 66.00 has it enabled by default (no INF setting required)

If you run an older driver than 61.77 then edit the INF and add to the following heading :


this line :

HKR,, D3D_35173345, %REG_DWORD%, 0x61243847

install with newly modded INF and like magic you have SM 3.0 support.
