When testing cards at below -64°C the NVIDIA driver gets confused and thinks the GPU overheats which causes a loss in performance.

When started with /fixcoldbug the attached GPU-Z build will increase the temperature reading that the NVIDIA driver sees by 65°C (it does not actually increase GPU temperature). This change should result in stable benching at lower temperatures.

Please note that a warm reboot might not remove the change, powering off the system and back on will.

Thanks so much for this!
Will be testing tonight and report back the results.
 
Ok so I just tested this for a bit, and I'm sorry to say it didn't change the cold slow bug any for me.

It did alter what temps gpu-z and precision were reading, at -65c it was around 0c. However the cold slow bug started at exactly -68c (according to probe), with or without the fix applied.
 
changes included in 0.4.3
