Might be nothing but I thought I'd pass it along. I installed the new patch via updater. Didn't start the game but instead did a reboot. I got back to the PC, was a while, I ate. First run of the game it starts OK, I find out where the squad's at, get to the runway and get a little screen freeze, sound cuts--it comes back for a few secs, does it again. I get a message that I read quickly in the buffer saying I didn't have enough video memory and it clears for another sec before locking up and giving me the aceshigh.exe has stopped working. I had to start the task manager to close the game. I ran it again the rest of the night without issue. <shrug>
I've had the aceshigh.exe lockup thing randomly. Seems I get it once a month whether I need it or not. This was different so I thought I'd tell ya.
FYI I haven't changed my config at all. No drivers, no software other than the update to AH in over a week.
