Low Hash Rate After Gaming

[hifieli]

Almost as annoying as rebooting, but a little faster: you can log out of windows and log back in.

However, if you find you have to reboot anyway, it might be worth the effort to setup a dual boot situation with a little Debian action on another disk/partition. As has been mentioned, you can squeeze quite a bit more hashing performance out of the same hardware and electricity by using GNU/Linux instead of windows. And you'll probably learn a lot in the process

I have the same problem but not after gaming, after restarting the cgminer and second GPU always gets slow hash while I'm doing this. Couldn't find a solution except boot and disabling the device via device manager didn't work. Any help?

press win + pause, go to device manager up left corner of the window- select display adapters - right clock on the device and disable - after right click again over the vga and select enable

This helped. Although having to resize all my windows like IRC, TS is quite annoying. But then again if it's the only fix, it saves rebooting

Thank you!!! I was having same issue with my R9 280x... going to half hash rate with no reason, or when changing mining algos.

It could be because the GPU temps is approaching the temp limit and it is underclocking itself to prevent damage. Try letting it cool down for a while then the hash rate should improve.
