I haven't done any benchmarking yet, but:
Forcing triple buffering with d3doverider hasn't really made much of a difference. GPU usage is interesting though. In JC2 (all i've tested so far) GPU usage fluctuates between 61%-95% when exploring the island and staying away from buildings. However, when facing buildings, which is when performance drops, I get a steady and consistent 56% GPU usage.
Triple buffering won't magically make fps higher, only provide the steady gpu performance of double buffering without the downfalls of vsync, which increases response time and therefore input lag and therefore Exodu5's tag. Basically you don't have the performance hit caused by render ahead limits, the tearing of double buffering, or the response time increase of vsync but the benefits of everything.
Onto the GPU usage, this is just a theory but if you're staring at a building there is little geometry to be processed which would limit the GPU usage. Z-culling is a GPU method to limit rendering to only objects visible by the camera saving your GPU from rendering things not on screen. So if all you are doing is staring at a relatively simple object like a building the GPU would have low usage.
I have just cause 2 and I'll fire it up and do some testing on my 470s to see if I get a similar problem.
Edit: Read up on you're previous posts and sounds like vsync is forced on or something else causing that frame lock. So recap is bad performance (or seemingly bad) as its either 60fps/30fps, you reinstalled everything, tried different drivers, tried d3doverider still seeing bad performance.
I always check my Just cause 2 and GPU usage fluctuates from 60-100% on both my GPUs but everything setting maxed except ssao and always +60fps.
Friend had an issue with 5770 where it would frame lock to 60/45/30fps and ending up reinstalling the drivers a few times till it got back to normal but we never got to the root of the problem.
Really wish I could help you other then say check driver settings to see if vsync is on by default. What ever happened with that monitor driver that showed up for you?
