WM 6.1 problem

[Oxymoron238]

Okay, I really need some help. I mentioned this lightly in another thread, but it was mentioned under another title, and people who may have been able to help didn't see it.

I'm having a serious problem with Windows Mobile 6.1. I can run programs with ease, but every time I run and exit a game, my phone slows down A LOT. The lag causes some of the programs I launch to freeze. The only way I can get my phone running at normal speed again is to soft reset.

I've tried hard resetting. I've flashed to three different WM 6.1 roms, and all of them had the same problem (these three roms are the official HTC 6.1 upgrade, Conflippers rom, and the super fast super stable Crystal rom, listed here in the order that I flashed them). I think the custom roms I tried are great, and I don't blame them for this issue. I really think WM 6.1 is to blame, seeing as one of the roms that slowed down on me was the official HTC release.

Does this happen to anyone else, or is something wrong with my phone?

(Also, flashing back to 6.0 doesn't fix my camera quality either, which also decreased by worlds when I flashed to the official Alltel WM 6.1 release)
