Thanks for the replies. I changed to the Catalyst 4.7 drivers, and got a slight frame rate increase. I can run the demo at 29 fps - the problem was that I needed to go into the console and start the demo immediately after starting the game. Previously, I was trying the run the demo with a previous level already loaded - and the system didn't like it. BTW - I prefer to stick to 1280 * 1024 resolution because that matches my LCD monitor. Trying to run at a lower resolution simply introduces artefacts as it scales a low res picture up to match the pixels on the LCD screen. Next problem - the game runs well for about half an hour or so, and then slows right down (big pause when you enter a new frame, jerkovision even thought the reported frame rate stays high etc.). Its easy to fix, I just need to quit from the game, re-start it and go again for the next half-hour. Suspect a memory leak, which causes this problem when the program has snaffled all of the free memory - anyone else come across this, or have a fix.
