I've been playing a mod called Brutal Doom, which is quite fun, with the GZDoom engine. Everything was fine until I upgraded my video card to an AMD Radeon HD 7970 (old card was an AMD Radeon HD 5870).

My problem is this:

Transparent textures do no allow you to see through them anymore, they are simply blacked out. I've tried playing with all the options in the Texture menu, but nothing appears to remedy this. I also played Vanilla Doom with the GZDoom engine and the same problem appears.

I had a problem with black boxes appearing around sprites as well, but enabling "smooth sprite edges" takes care of it, thankfully.

Anyone else run into this problem or found a fix for it?

Are you using the HQnX x4 filter on textures? It looks like it. If so, turn it off, or bump it down to x3.

While I have never seen a transparency loss on these textures with it, I have seen it on some other textures. I see you've found the thread.

Oh yes, the HQnX x4 filter was on. I was just testing it out because the latest release of Brutal Doom has some new higher resolution textures and I was trying to normalize the difference between the old and the new. I usually have it off as I prefer the pixelated look.
But even if the filter is off, it does nothing to make the transparent textures work properly.

That is more interesting. So I guess HQnX was not the culprit here, which at least explains why I never had problems with it and these textures in particular.

If you go to the texture options menu, what is the texture format? If it isn't RGBA8, try setting it back to this.

If it isn't that either, the only remaining explanation is the upgrade from Radeon HD 5870 to Radeon HD 7970. Did you entirely uninstall all the old drivers, and did you update the new drivers? I'm not really an AMD/ATI specialist, so it's a shot in the dark.

Yup, the texture format is RGBA8. I tried all of the texture format options and still no dice.

When I installed my new card I didn't uninstall the old drivers, I just installed the new drivers on top of the old. Doom appears to be the only game giving me grief, but I think it's well worth doing a full uninstall and installing the the new drivers clean.

Success! The clean install did the trick. Thank you for your help, Gez.
