I was not hit by any ground fire, as there were no AA emplacements or SAMs in the area. I was not damaged by another plane, as this was happening before my flight even engaged the enemy F-4's.
I tested it again on a bomber intercept against IL-28's and I notice this happens whenever my speed exceeds 800 knots IAS. So, I'm beginning to think it's part of the plane's modeling to simulate the real MiG-15, although I still haven't been able to confirm that MiG-15's in real life had this issue. It's almost as if the plane wants to stall, it begins to act random, and whichever wing it wants will begin to dip downward and the whole plane begins to shake. I'm thinking this is a feature of the FM and not an error.
ALSO some great news! All of my settings are back to unlimited on Strike Fighters 2 with absolutely no loss in FPS. My frames are now sticking around the 40-60 mark! The culprit?
When I updated my Nvidia drivers, I elected to do a clean install, as I had begun to think my previous drivers had somehow gotten corrupted. The clean install of my drivers absolutely solved all the problems I was having, right up until I got into Strike Fighters 2. I was baffled. Well, it turns out, in my Nvidia Control Panel Settings, Vsync was forced on for Strike Fighters 2 (apparently a default setting for Nvidia Cards)
I do not know why having Vsync enabled in the control panel was the cause of all my problems, but turning it off has solved everything. Admittedly there is a very tiny amount of screen tearing if I pan my view really quickly in the cockpit, but that does not bother me in the least. What bothered me was the absolute garbage for frames I was getting in one of my most cherished games, lol.
Apparently an older game like Strike Fighters 2 does not like Vertical Synchronization enabled. Which is strange, because I don't have that problem with any of my other games.
So for anyone who may be having the same mind-boggling, infuriating issue where you have a machine more than capable of running Strike Fighters 2, but it's suddenly running like crap, check your graphic card's settings and see if it's forcing something.
