Would it be possible to have some clarification on the issue of Ati cards staying at low clock speeds? This has been improved for me with the last beta patch as it went from "desktop mode" 240Mhz up to 500Mhz when i'm in the sim, but it still won't go up to 850Mhz which is the maximum (non-overclocked) factory setting for my 4890. The difference is that it runs at 20-30 FPS at 500Mhz, while at 850Mhz it can easily go into the mid 50s.
The reason i'm asking is that maybe we could help resolve this faster. For example, is it something that will have to be patched in the sim to enable catalyst to recognize a game is being run and throttle up the GPU, or is it a driver issue and we're better off reporting it to Ati/AMD directly?
If any of you fellow with access to the Russian forums could tell us about any possible information on this issue it would be much appreciated
I used Ati tray tools to force the clock speeds to 850Mhz but i don't know what other settings to use (cooling fan? voltage? etc) to keep the GPU running stable.
I do get 50 FPS over most kinds of terrain, 25-30 over London and 20-25 in the Black Death track with the clocks set that way, but it ends up rebooting my PC after 40 minutes or so.
This doesn't happen in any other game where catalyst/drivers automatically runs the GPU at 850Mhz so i doubt it's an issue of overheating (GPU temps hover no higher than 60-65 degrees anyway), but i don't know what kind of other settings the drivers possibly change when throttling up the GPU.
