RX 480 strange GPU activity chart

Hey everyone,


I've had my RX 480 for a few days now and can't really complain too much about the performance. However, Wattmans GPU activity chart looks rather strange to me. No matter what game I play, I constantly get spikes, with activity changing between 100% and 0%, looking like this: Imgur: The most awesome images on the Internet (that chart is a dota match, not the most demanding title for sure)


I've never seen this kind of erratic behavoir with any of my previous GPUs, nor in any Wattman charts I found online. I thought about this being some kind of CPU-Bottleneck, that system is only running a G3258 (although OC'd to 4.4Ghz), but I never encountered something like this with a GTX 970 I used for a few weeks.


So... does anyone have an idea what causes this strange activity behavoir?


Thanks in advance!
