This is proof that GLSL shaders 1.20 is passable but should not as it is unstable or worse unplayable.
If people see's this test with NVEDIA. even than of how it performs might be bad for some games.

I validated that DXGL works with NT 4, but it is slow in software rendering. Still, if you have NVIDIA graphics you might have a better experience. Yes, DXGL Works, however, I did not test GLSL shaders 1.20 due to unplayable with under-powered FPS., only game that was tested was Scooby Case File #2 stone dragon with super debug mode, by removing visual quality and effects. Which from my perspective can't be done without hacks from the TLC engine. It does work with GLSL shaders 1.20. Still just use 1.10 if you really want to test. Even then you're better off with FunkyFr3sh / cnc-ddraw.
Due to Williams' credit the developer of DXGL, it does work with sample games.
As mentioned both in my correspondence in this thread and in the Downloads page, this build is experimental. The changes however have been merged into master in order to allow them to be incorporated into a future release.
I never really thought of supporting Windows NT 4.0 but this thread kind of pushed me to do so.
About that OpenGL32.dll you included in your logs, is that a version of Mesa by any chance?

That OpenGL32.dll is indeed from MESA the only one I found with GLSL shaders 1.20 support that might be broken. again, I only advised the 7.3 release.
I mostly TEST 200+ educational games. I've seen a performance hit of 20 fps in 70% or odd crashes in the 7.5 release it is really not advised.
