So, i decided to install Requiem: Avenging Angel on my old Windows Xp workstation. I followed a tutorial for bypassing the DirectX 6 restriction and updated from 1.2 version to 1.3 of the game.
I decided to play it a bit and i encountered many problems in Direct3D graphics. The game itself tends to crash a lot, sometimes it staggers and when you save or load it tends to freeze and then crash. I tought it was a problem with Direct3D graphics, or even framerate too high, but it turned out not to be the problem (for some reason in Software mode doesn't give problems).

So i tried to put it in 3DFX via the patch and nglide. And so it shows the option to put it in 3DFX.

The problem is that when i start it, it gives this error:

And there's no way to make it work, from what i tried to do to fix it. I tried to rename the icons, tried to add a 3DFX subfolder in ART folder, but nothing works.
