Same thing was happening to me, but I just noticed that it is the case only when I set fps cap in RiviaTuner.
When I let it go uncaped usage spreads almost evenly throughout the cores and is around 40%, ingame sync doesnt affect it for me...
Bad news is if i dont cap it at 30 my gpu will be at 99%
Anyone experiencing same thing?
