When playing most games my GPU usage idles around 50-70 and rarely goes into 80 and never into 90. I have a Sapphire 7870 GHz Edition and it's driving me crazy that the GPU usage is not staying at 99 constantly. Here is an image of the GPU Usage and my CPU utilisation while I was playing AC:IV at high without AA
Heat is definitely not an issue here, I have the latest 14.3 drivers installed, my PSU is more than enough so I am really stuck on what could be causing the GPU never to hit 99 or even 80 in most cases. I've tried rolling back drivers, but that didn't help. It is definitely not a CPU bgottleneck and I've tried overclocking it to 4.00 GHz to no avail. I've tried setting the power limit to +/- 20%, but that hasn't made a difference. I've tried overclocking my GPU, but that didn't make a difference either.
ONLY WHEN THE GAME IS MAXED OUT DOES IT STAY AT 99 but it is useless since it is barely playable by then
My other system specs are:
CPU-FX 4130 3.8GHz (Zambezi)
PSU- Corsair CX600M
RAM-8gb DDR3 1333Mhz
