Performance sharply drops while staring at cap ships

In some missions (perfect example and current point I can't get past due to it) like Hyperion 4, staring at most cap ships results in performance shooting down in to single digits. Sometimes, when I stop changing my angle of view and stare straight at the cap ship in question, the performance will go back to normal, others, it will just stay choppy until I look away.

This is tolerable for dog fight missions, but I've got to stop CShip missiles... That's impossible right now, even in the Excal

Have already tried disabling GLSL, running lower settings blah blah blah, [EDIT]Thought it was fixed, but it persists once you get to the armageddon and have to dogfight with the bombers. Problem resolves itself at times with lighting level 3 with GLSL disabled, but looks crap

I would believe it to be an unfixable issue if it were persistent, but being that it only happens when looking at cap ships... No fun.

I can upload a video if it would help.

Yep. Definitely forgot to reply after getting a couple more missions in

You should definitely compile an ATI hot fix patch and give it 3 options in the installer

ATI OGL dll file (Should fix 90% of issues by the looks of it )
Disable GLSL
Rock fix (Stupid asteroids XD )

That DLL is a god send, and my googling never hinted it would fix anything. Without the random wisdom, I would have rage quit and stopped playing
