Hmmm... it doesn't look like I'll be able to run F@H optimally. I ran the tracker, set everything up and got just the GPU to do the work. However, there's the most annoying modulated high-pitched whistling sound coming from the speakers and also directly from the graphics card. It's clearly audible and not possible to ignore, so it's no go. While I didn't expect the audio breakthrough, I expected the graphics card to make some noise, from previous experience of driving cards at very high framerates. I guess I could throttle it back a bit, but it's still gonna make a noise, just less, so it's pointless. On to the CPU: I can only run the single core client right now, because the cooling isn't up to it. My Zalman cooler is analog and has a resistor to run it at a constant slowish speed for quietness, which it does very well. This is fine for everyday use and games (just about) but the CPU was climbing the high 70's before I quit the client. In fact, I had to kill the client with the Task Manager too, because the tracker couldn't stop it. :shadedshu So there you go. I'm gonna continue to run it, just not with the performance us enthusiasts would like. Any suggestions for improving this situation welcome.
