Pixel shader enabled = filtering problems, odd?

[Martin Crozier]

Hi wondering if anyone's seen this - REALLY odd:
I have an A-Tek radeon 9100 128mb DDR (card, not the IGP version) -
latest catalyst drivers (3.10), latest XP patches etc. On Call of Duty I
notice that on any level that uses the pixel shader effects in openGL (which
isn't all of them, but usually most of the SP levels and some of the MP
levels that have water effects etc..) the texture filtering appears to
disable itself; i.e. no bilinear or trilinear effect, just jagged unsmoothed
"raw" textures... The game speed is slightly effected due to this, I lose
about 20-30 fps on SP levels and about 10fps on MP levels. When i edit the
video config in CoD and change a value and reenter the game, the textures
are fixed for some time until i come across more pixel shader effects on
screen and then the textures "snap back" to their jagged unfiltered states
again. This only seems to happen in Call of Duty since I upgraded the video
drivers, however ive tried older releases of the catalyst (3.7, 3.8) and
nothing seems to fix it!

Any ideas anyone? This is annoying me.

MC.

I've reported this here and in the Rage3d forums-
a grainy unfiltered look on some textures (not all)
in CoD and Knights of the Old Republic with 3.10s
- both games are OpenGL. I've gone back to the 3.7s
and all seems okay tho performance in KotoR is poor.
I didnt know CoD used pixel shaders - KotoR does and thats one reason it
performs badly but mainly I think ATI
can't produce a decent OpenGL driver.

It would be rather more productive to report it to ATI.

That would be why ATI usually outperforms NVidia with OpenGL & D3D
benchmarks then.

OpenGL guy will probably read it. He may have posted the poblem in Catalyst
Makers "Unofficial" problem thread.
