These were all run with the first timedemo at 640x480, and (for the open source drivers) with ColorTiling turned on in the xorg.conf file. I'll list all tests with the open source drivers first: x700 + r300 (with arb renderer) - 5.5 FPS (There's not much point in testing it with the r200 or arb2 renderers at the moment.) >>> What's the problem with arb2? >> >> fragment.position input is not implemented yet. fglrx driver parses >> it from VP to FP via a texcoord route.

I would really like to capture the vertex program of program/fp/tri-depth and the fglrx driver. But I'm betting the vertex shader is capable of writing to a texcoord. All I need is a safe way for the vertex shader code to know if the fragment shader needs the position. Any help with this would be great. Rune Petsen - Using Tomcat but need to do more?

[Bug 7861] New: mach64 with render acceleration should restore texture state
Please do not reply to this email: if you want to comment on the bug, go to the URL shown below and enter yourcomments there. https://bugs.freedesktop.org/show_bug.cgi?id=7861 Summary: mach64 with render acceleration should restore texture state Product: Mesa Version: unspecified Platform: PC OS/Version: Linux Status: NEW Severity: trivial Priority: P2 Component: Drivers/DRI/Mach64 AssignedTo: dri-devel@lists.sourceforge.net ReportedBy: [EMAIL PROTECTED] Spawned from bug #6877. RENDER acceleration uses texturing, thus when RENDER acceleration is enabled, the mach64 DRI driver should restore texture state when acquiring the DRI lock. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. - Using Tomcat but need to do more?
