I have an Athlon XP2000+ with 1GB RAM and a Radeon 9600Pro running on an Abit KG7 (capped to AGP 2x due to MB limitations).
The errors in the game (new user) are... numerous. Starting location- the trees are invisible and appear masked over other object's polygons (see screenshot: http://www.unciaa.com/stuff/secondlife_bug1.jpg), my own avatar is completely invisible, others' are but a tiny head with its polygons extended into a pelvis-height hovering sphere. The water's waves literally eat the shore in the distance with every wave, the boat's texture is a whim and walking down the hill causes object polygons to begin covering the screen until the game freezes entirely and requires a reboot unless windowed.
Tried so far: Catalyst 4.7, 4.7, Omega drivers, FastWrite On and Off, AGP on and off, game reinstall, display options maxes, display options killed completely, video memory halved, texture memory doubled,... to no avail, the errors remain exactly the same every time. Except that the grass texture looks higher resolution with the display maxed out.
I doubt my hardware is to blame, it runs everything else fine, including Doom3. No artifacts of any kind there to suggest overheating.
Any ideas? Except "get an nVidia card come next upgrade"?
