Just throwing this out there... But, I have the same issue. One thing I did notice, though, was it has something to do with tweaking the video settings. I have a new rig, but the game runs pretty bad as opposed to running flawlessly on an older PC. So, I turned all the video settings to the bare minimum. From there, I started tweaking things back up to find a good balance. I haven't been able to figure out exactly which one was doing it, but I had the same problem. I'd constantly RGL Error crash after battles, talking to companions via party menu, entering towns, taverns, etc. It's been a while since I've played Warband or Perisno, but if I remember correctly, I was leaning towards it being a Direct X 7 and Direct X 9 issue. I --think-- it was trying to run Dx 7 with most things as low as they'd go, and turning other things to Max or High and it crashed. Switching to Dx9 and doing this seemed to fix it. Or, it's the complete opposite. I'd have to jump on sometime and mess around with everything to try and narrow it down again.
