Re: [Dri-devel] Slow Mtex in DRI

2004-02-17 Thread Chris Ison
I have lodged a bug report reguarding mutlitexture being slower than multipass with radeons and DRI with mesaGL at http://sourceforge.net/tracker/index.php?func=detail&aid=899074&group_id=3&atid=13 as I feel this may be a mesaGL bug that effects DRI. But please correct me if I'm wrong.

Which hardware/driver are you using under Linux? I just became aware of a hardware limitation in several drivers (mga, r128, savage). They can do multi texturing, but if multi texturing and projective textures are used at the same time they fall back to software rendering. For example quake2 gets

I'm no expert, but with mtex dose more TMUs help? If so you should try with the patch, I have had 6 enabled with no problems or use. Also how can I help get this patch commited? I can run test programs. The patch should be in list arcives dated... Sat, 3 Jan 2004 00:30:35 +0100 Sun, 4 Jan 2004 1

[Dri-devel] Slow Mtex in DRI

2004-02-14 Thread Chris Ison
I have found something disterbing about DRI and was hoping you would be able to give a solution.   It turns out, through recent QuakeForge changes, the DRI is faster in multipass rendering than with multitexture (mtex) rendering. The same method, and with no alteration to the code, with nVid
