Summary: Regression, maniadrive very slow (rast fallback?) and
wrongly rendered
Product: Mesa
Version: CVS
Platform: Other
URL: http://maniadrive.raydium.org/
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/r300
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Hi,
I'm using a radeon 9800 pro, x86_64, Fedora 8 test 1. Fedora 8 test1 comes with
Mesa-7.0.1 (I choose CVS as version as 7.0.1 isn't in bugzilla yet). I'm a
Fedora developer and currently I'm working on packaging maniadrive:
http://maniadrive.raydium.org/
If I downgrade mesa to 6.5.2 (from F-7 updates) and disable shadows maniadrive
works well (with shadows it becomes very slow).
But with 7.0.1 it is slow even with shadows disabled, I do get this message:
*********************************WARN_ONCE*********************************
File r300_vertprog.c function r300TranslateVertexShader line 1130
Ran out of temps, num temps 13, us 12
***************************************************************************
So I guess the recent r300 vertex prog rewrite is the culprit here.
And after this Fedora update:
* Thu Aug 16 2007 Dave Airlie <[EMAIL PROTECTED]> - 7.0.1-3
- mesa-7.0.1-stable-branch.patch - Add patches from stable branch
includes support for some Intel chipsets
- mesa-7.0-use_master-r300.patch - Add r300 driver from master
It stayed slow but also become wrongly rendered (all textures seem to be
missing)
As said I'm a developer / programmer myself, I have almsot no experience with
3d hardware programming, but I'm veru skilled in C and debugging in general. I
would really like to see this fixed, so please let me know what I can do to
help.
p.s.
I'm afraid maniadrive is a pain to install from sources, let me know if you
need help with that, if you use Fedora I can provide rpms if you want.
