Re: Destruction Derby for DOS slows down a lot under Windows 9x

I was never able to reproduce this issue, but rev 932 addresses what I _think_ the bug was. TheMadLynx, if you're still around, could you try this commit? I've tried Pyl with 9b72b24 commit. It is not perfect but definitely a huge improvement. Game gets into main menu almost instantly, like on real...

Re: 8086 emulation

Programs not working in 8088 emulation: -norton commander -lemmings1 -titus the fox When running them, the pc just stays forever in a black screen. I'm sure that it is a native 8088/86 behavior due to the lack of CPU instructions needed by complex programs created much later than a PC XT. Replacing...

Re: Destruction Derby for DOS slows down a lot under Windows 9x

Just for the sake of comparison here are screenshots of the same game running on the same machine with the last public PCem v12 build (Feb-17). Overall performance is much better and more consistent.

Re: Windows 10 problem

THERE are sources and text information files and no roms. Open Google and ask "pcem roms" I guess even the first link will make you happy.

Re: Destruction Derby for DOS slows down a lot under Windows 9x

And here it is: the config file and some screens to illustrate the problem. As I can say it is not very game specific. Dreams to Reality lags much the same.

Re: Destruction Derby for DOS slows down a lot under Windows 9x

And I am one of them. Some DOS programs shows abnormal low performance drops (15-30% with P200) with any pentium cpu selected in actual PCem builds. I've tried Dreams to Reality and Pyl (Dust) with the PCem from 18.07.2017 (commit 16a453b). Performance stutters most noticeable at a game launch. Also...

Re: Jagged Alliance not Install in DOS 6.22

the only unusual issue is the pentium recompiler slowing down in a lot of it (13-40%) and that's nowhere near fatal. Game is fine and dandy on 486 recompiler however (which is fine as it doesn't need more than a dx2/66 to be perfectly playable.) I've noticed that some DOS programs shows abnormal lo...
