So I've started playing on a system for 2001-2003 era games which it should handle fine, and for DX7,8, and early 9 titles it does great, but OpenGL it just falls apart.

System Specs
Athlon 64 3200 939 Venice E6
ECS KV1 K8T800 Chipset
1GB 2x512mb PC3200 2.5-3-3-5
Saphire X700 Pro Tried Cat 6.12, 7.2 and 8.1
Windows XP Pro SP3

So what happens is the games I've tested so far Medal of Honor Allied Assault, Jedi Outcast, Jedi Academy, Call of Duty anytime a firefight or any sort of effect FPS drops from 90 to around 20FPS, driver revision doesn't seem to matter it just turns into a stuttery mess. Settings are High across the board 1280x1024 with simple shadows. Anyone got any advice, I mean I knew ATI was bad at OpenGL, but i dind't think they where this bad where it goes basically unplayable.

Try Catalyst 7.11.

I'm not sure if it will improve performance, but it should be more compatible with OpenGL games than later versions. See swaaye's notes on the download page for more details.

PC#1: Pentium MMX 166 / Soyo SY-5BT / S3 Trio64V+ / Voodoo1 / YMF719 / AWE64 Gold / SC-155
PC#2: AthlonXP 2100+ / ECS K7VTA3 / Voodoo3 / Audigy2 / Vortex2
PC#3: Athlon64 3400+ / Asus K8V-MX / 5900XT / Audigy2
PC#4: i5-3570K / MSI Z77A-G43 / GTX 970 / X-Fi

7.11 had the same issue but I went all the way back to 5.13 and my issues are fixed. Not sure what the 5.13 drivers do diffrent than the 6, 7, or 8 series drivers

It's one of the Rialto AGP bridge cards so that could be why. The drivers are rather unpredictable with them.

Yes I'm not sure either, if I could get a working 6600gt or 6800 series ago I'd just go that route. I've been tempted to swap to a pice board and a quadro fx3450

I just tried Medal of Honor: Allied Assault and Call of Duty with PCIe Sapphire X700 Pro using Catalyst 7.11 on WinXPSP3 and both games worked fine with stable 60FPS, so seems swaaye could be right.

Only thing I noticed with both of them is neither one has a working in-game V-Sync, MoHAA had weird frame pacing issues while Call of Duty had visual artifacts during the first mission with it on. Forcing V-Sync on in Catalyst Control Center made both games work great.

Yea must be the bridge chip then.
