Low FPS with low GPU & CPU load

[baldursgate3]

I'm getting pretty bad FPS when playing Garry's Mod.
My CPU is Intel Core i5 2320 and my GPU is GTX 670.
I also have 16GB of ram.
Does anyone have any ideas of what might be wrong?
Or is it the Havok engine being bottle-necked?
EDIT:
I tried overclocking the GPU but it didn't change anything.

The maximum with full AA?
By the way, i noticed that reflect all setting impacts my fps badly. It shouldn't really do that.

Im gunna say have you tried updating drivers, that usually fixes things. Although i have seen things on the steam forums about games that use parts of valve's engine running laggy on high end gaming pc's

I get occasional dips under 60 on my rig, and that's just on TTT.

Just to make sure: You have vsync turned off?

No, i do not.
I turn on Vsync so that my card doesn't heat up and make loud noise.

Turn vsync off and you should see better FPS. Cards are designed to run hot, and you're just limiting what it can put out.
