Three apps using plain DOSbox run fine on my Windows Vista, 7 & 10. Another App, FC-Compiler, using DOSbox SVN Daum version, runs fine on Win Vista & 7 but not Win 10. Win 10 runs on a new HP laptop. When running DOSbox SVN Daum by itself, I'm able to get into it and 'mount ...' cmd works. Typing is a problem, it rapidly duplicates letters ... trying to type exit cmd, often gives EXXXiTT.

What is the best DOSbox Configuration settings to get the speed of a 5 year old HP PC running Win 7?

Would such settings slow down older PCs running my FC-Compiler app?

Thanks,
Phil
