Timing for DOS games played through Windows XP

Obey the Daleks or be Exterminated! Riiiiiiight...

In DOS games using VDMSound and CLI2NOP, the framerate for the games move about 5 frames slower at 59.940 fps (2.5 frames slower at 29.97 fps), due to the sound.

Would it be feasible to speed up footage of DOS games played through Windows XP when VDMSound and CLI2NOP are used to get the time for games without timers?

Never give up!

Just discovered this on a search to find out if there had been an actual ruling on whether VDMSound was even allowed (I didn't find such), and....

I think adjusting the video's speed is a bad idea. Unless you can prove it doesn't do weird things to the audio. We should instead divide the time (I say divide because it will inevitably be slower) by a set amount. Much like Game Boy games run on a Super Game Boy (even though that's multiplying instead of dividing), or PAL timing for Mario Kart 64.

I'm addicted to games

do you really think playing a game at 1/5th the speed the game is supposed to run at and then speeding it up in the final video would be valid for this site? I think there's another site for that practice.

I rethought the question that was being asked, and....

You're simply losing frames, right, Serious_Cacodemon? If that's the case, speeding up the video or adjusting the timing would be pointless. You're smarter just taking the frame rate as it is.

If the gameplay itself is actually slower, that's an entirely different matter - there's no point in even trying THAT.

Maybe you could show us 3-minute samples with both of those programs running and without either one running (which would be video-only, admittedly), so we can get a better idea what's going on? (I say 3 minutes because there will be a definite difference by then if the gameplay itself is slower.)

Radix: Exactly. That is why I'm redoing the entire run at it's normal speed, so I don't have to end up changing it to it's normal speed. The game time however, will still be shown in the automap screen, which I did after I pelted enough Wraithverge ghosts on Korax and went to the wall where the end of game portal would be.

Aquatiger: Even with VDMSound, Hexen ends up running pretty slow when sounds are being played. With CLI2NOP or IDPATCHR, game speed is reduced a bit and the music and sound aren't good. I'm unsure if I have the original VOB files for my previous segmented attempt, but if I do and I get some more segments done for my actual submittable attempt. I was thinking perhaps doing it with the Wolf Chapel, the previous attempt (unmodified in sound or framerate)
