Issues, Workarounds & Localization

I run a low-end laptop but have always been able to play EVE on low to medium graphics settings without experiencing lag.
My current settings which I've used since starting, I have AA, Post Proc and Shadows off, both interior settings low, textures high and the rest on medium. Resource cache enabled, no HDR.

Now with the same settings, I went into an l3 security, (Driving the wedge part 1) which I have done several times before without any lag issues. When I got in however, after 10 seconds the audio started to stutter (my windows media player too even though my laptop wasn't lagging.), after 20 seconds I was experiencing mild stuttering and lag, and about half a minute in it got to the point of so much stuttering and lag, it took me 3 minutes to finally get a warp command registered and save my ship.

I cannot find anything wrong, lowering settings still causes it albeit very slightly slower. I can still run the game without issues flying around and such. Anyone else have an idea what is causing this issue during combat?

Any assistance would be highly appreciated. I can't go out into any fights now since I'd lose my only battlecruiser.
