When i first start up my PC, the card (Sapphire Vapor-x 5770 1GB) will work great and get great framerates, but it will run around 80-85 degrees Celsius under load. However, if i let it idle for 15 minutes, the card runs at less than 65 degrees Celsius under load(never goes higher, even in furmark), and my framerates suck. Is this a driver issue? Anything i can do?
Perhaps you can try updating/reinstalling your driver, as that is always a good first step, but since you say it runs into this problem after 15 minutes, perhaps there's something triggering it?
Is it always after 15 minutes, or does it vary?
