Hi,

Since the website http://www.racecarsim.com/ is up with addon cars and tracks I really wanted to replay this little gem of the past.
However Sports Car GT (SCGT) has allways been a pain in the lower back to get running ever since I bought it in the late nineties.
Some of it, I think, has to do with the game release I bought (cd label: SPCAR_152UK) which gives errors not finding files when loading certain tracks, which in turn means you can't play a championship as half of the tracks will crash the game. I actually repurchaced a later version which came in a dvd case, hoping this would be solved, but it turned out to be the exact same print. Anyway, this hasn't got anything to do with dgVoodoo.

First I couldn't get the game to run at all. I tried nGlide, which worked for me in the past but I think recent driverupdates from AMD older game compaibility went down the drain (as is v-sync control, which now you can force on but doesn't do anything 😤).
dgVoodoo worked for me in both 3dfx and Direct3d, but both also have issues. 3dfx Seems to be the most compatible and everything is displayed like it should, however this game was released with terrible filtering limitations, so everything further than 30 meters away looks extremely blurry. So I was hoping if there is a way to turn anisotropic filtering on?
Direct3d is very good too but certain elements are not displayed at all, the sky is completely white and cars are missing textures.

Sounds like the usual AMD driver problem with D3D11. Did you try D3D12?
D3D version of SC GT should work just fine (I tested it with 2.7) and unlike with the Glide version, you can force anisotropic filtering with that.

Hey Dege, 😀

I have a Radeon RX 580 4GB. I don't understand what you mean with trying D3D11 and D3D12.
Do you meant the D3D9.dll in the MS x64 folder? If so, yes I've tried that one too.

No, I meant D3D12 as output API in the dgVoodoo configuration (General tab).
Also, you need DDraw.dll and D3DImm.dll from the MS x86 folder because Sports Car GT is a pre-DX8 game (32 bit).

Ah, I see now.
And yes, I just tried Direct3D 12 (feature level 12.0) and everything looks allright.
Thank you Dege! 😀
