Everything running perfectly fine with A7 Pro 7.82.3

Athlon XP 3800

Win XP Home


But now it comes...
I jsut tried with the brand new beta 7.83.7 where the string bug was fixed. It crashes wildly. An invalid memory area ix_import_GameData message popped up, problems with st_stencilBlur.fx (can't open file), and afterwards an E1513 in ix_Npc: SYS - endless loop.
A second time no E1513 popped up and I was able to play. But it was extremely jerky compared to the public release. Also the script compiled twice as long as with the public release.
