This is the lowest I got the game without crashing, Sorry for the delay :/
btw I didn't have any problems with my vita frying so idk what OP is on about, there was no HDR function in Unreal Engine 3 as far as I know.
And if your using a vitamin dumped version, or a pre 1.09 mai dump it may crash at the main menu although for 1.09 mai dumped version, it seems to work just as usual.
Expect anywhere from your regular 15fps-60fps, but usually somewhere inbetween with using oclock vita. In the future I'll post a full tutorial on (

For the resolution change, it seems to crash on any version when editing the coalesed_INT.bin resX, and ResY settings but there are ways to increase/decrease resolution from editing the eboot (I'd asume using a hex editor) as a dude from (
https://www.reddit.com/r/vitahacks/comments/637np7/problematic_psp_game_fixes_force_unleashed/) said he was able to edit these. Idk how he did it, might look into it later.
