[r85] Texture screwup

Vaecrius · Post by **Vaecrius** » Mon Apr 07, 2008 0:29

After playing for about a minute or so my textures suddenly warp. It seems to happen when I fire, or when things get busy.

Specs:

HP Pavilion dv6607nr
NVidia GeForce Go 7150M
Windows Vista Home Premium
Drivers: Uh... whatever the automatic update thing does.

I'll try a new driver after this post, but I can't reset just yet.

Please try again after entering 'gl_clamping_bug 1' at the console.

I'd also get this same texture corruption when playing Strife.
gl_clamping_bug 1 fixed it for me, yeay!

It would always happen when I first went to the Tavern, and entered the room where Harris is.

Just out of curiosity, is this a driver issue? I get this on both a Radeon 1950 and Radeon 800.

I remember that (much) older versions of gzdoom didn't do this, but I just assumed that something was funky with my copy of strife since I never seem to get the texture problem in doom or doom2.

It's an incompatibility. The problem is that some newer drivers handle the clamping information differently and changing it repeatedly severely brings down performance (we are talking up to 50% performance loss here). so I have to cache it internally. But some older drivers can't handle this properly and I had to implement a switch into the engine that allows both to function.

The cvar fixed it, thanks!
