GPU not fully utilized?

[Riku_22]

So since i upgraded my gpu (gt9500 - r9 270x) my gpu usage is around 20% - 40% at most. This is really annoying because my frames are below 60fps and the game stutters a lot. I play on 1920x1080 with the highest settings. the frames dont change even if i lower the settings/res.

My cpu usage is also around 20-40%. Both the cpu and gpu temps stay well under 60 degrees. My game is loaded on a ssd so there should not be hdd bottleneck i think. Does anyone know what to do? The game is unplayable like this. This only happens in mx bikes. Any other game seems to fully utilize my gpu.

my system specs:

cpu- i5 3470
ram- 1x8gb ddr3 1600MHz
gpu- AMD RADEON R9 270X
Storage- 128gb ssd and 2tb hdd( mx bikes and mods are on the ssd with windows)

Any feedback would be apreciated!
