Graphics cards and Discovery?

[Exploration]

As the title states, there's something a bit strange going on here.

For some reason after a reinstall of the game, my GTX graphics card won't jump to the boost clock with Disco running. Or anything above 300mhz for that matter core wise. The other thing I've noticed is the game will run at 45-50FPS like this - This aspect drives me crazy because for the past few months I've had a locked 130 and now it feels really /really/ slow. However if I fire my guns in game for example, the FPS spikes to 179 and then drops to say 130FPS. When I stop firing altogether it floats back down to 45-50. Again virtually unplayable for me just because it feels so slow and it fluctuates so badly depending on what you do. I've spent a few hours googling this and can't seem to find anything that looks like the problem I'm having.

I've so far tried disabling V-Sync in Nvidia's control panel. Enabling 'K Boost' in EVGA's Precision X (Basically forces the GPU to run at full power regardless of load). Still the same issue occurs. Literally don't know what else to do at this point. I'm wondering if maybe my Intel card is interfering here somewhere as recently I had to reinstall a bunch of graphics drivers due to the Windows 10 Anniversary update screwing things up. -

Spec: Intel i5 3570k + EVGA Nvidia GTX 750 Ti (FTW Edition). Note I run the Intel Integrated along side the Nvidia card for my secondary monitor only. Just because my main GPU doesn't have a VGA port on it. This has run this way fine (even though I know i can buy a DVI to VGA adapter)


How do make Freelancer not do this weird FPS stuff/like my gear. Thanks
