I also have the flickering problem (SR caves and SR for what i have seen until now).
Here are the info:
Video card: ATI Mobility Radeon X1400 x86/SSE2
Vendor ID: ATI Technologies Inc.
OpenGL Version: 2.0.5524 WinXP Release
I have tried to turn on / turn off the vbo and the frame buffer, but it seems nothing changed.
Everything else seems to work fine for me. I'll use the RC for a while and report if I see anything else.
