Event log: nothing. Crash is to sudden.

Anyway, graphic problems can't explain slow performance in recompiler mode.
Note that there is no crash in interpreter mode.

Recompiler works at 30 MIPS and more just a few seconds, then slow down to
2-3 MIPS, and a few seconds or minutes later, everything crash... even if I
leave the application before problems.

As if the processor didn't manage to execute the generated instructions,
and just finished to stop after too many errors. Under VPC7, the problem
was the same, with an illegal instruction error (sometimes) and some
massive slow down (everytime).

Classic limit of the first Atom: the Bios choose the available instruction
set. You can't change it later.

I'm not very lucky with my computers :(
