You can run cefclient with BOX86_NOPULSE=1 /opt/ocean-wine/bin/ocean-wine in box86, cefclient.exe need full path

Thank you, I'll try to reproduce later. Note that I will not be much availble in the next week, so it may take some time...

When set BOX86_DYNAREC=0, disable dynarec, memory half less than before, but too slow.

@ptitSeb Dynarec use a lot of memory, how to analyze memory usage ?

[ptitSeb]

Well, yes, dynarec use lots of memory, because it maps all the memory the program use. Everything is in custommem.c. I guess it's mostly the memory "jmp" map that is the issue, but I don't have any alternative for now.

@ptitSeb

I read "jmp" map code, box86_jumptable malloc 256kb memory, set to arm_next. Is it necessary to consume so much physical memory? I try to set box86_jumptable malloc16kb memory, use memory less, dynarec works fine.
