Ultimate Doom Lag

[xboxmods]

I just bought the doom collection from the steam sale, but I'm having issues. Ultimate doom is virtually unplayable. I have tried on my laptop, as well as my desktop, but both exhibit the same issue. The game will play at full speed up to the point where I pick up an item. At which point, the screen stutters, and the black bar on the upper half of the screen turns to yellow. It clears up in about a second, but it makes the game virtually impossible to play when it freezes every time I pick up an item. Anyone know how to resolve this issue? Thanks.

It's because the steam version of Ultimate doom uses dosbox to run the original game. Running the original version in a dos emulator is more system demanding than just running the game native through a source port. I suggest you go download a source port and use that, this will solve any problems you are having.

ok, I'll look into it. I can't imagine it would be that memory intensive though. This isn't a high end computer, but I'd imagine it's capable of playing doom, emulated or otherwise.
Specs:
AMD Athlon II X4 630
2x2gb g.skill DDR3 1600
ATI Radeon 5770
Windows 7 64 bit

Also. I don't have the same issues with doom 2 in dosbox. I've also used dosbox with other games outside of steam, 7th guest, NFS, Wolfenstein, etc with no issue. As I said, I could be mistaken, but I wouldn't think it to be more demanding than the many modern games I play today.

I bought the Doom pack and i would like to know if the referal link is included ways to play with mouse look and stuff like that?

[AtlasRapture]

Yes source ports like Doomsday have mouse look, support joypaads as well as adding loads of new options and a few graphical encancements.

[ZeroSignal]

Yes, absolutely. If you want extra features like mouse look, jumping, crouching, etc.. go download ZDoom (or GZDoom if you want OpenGL support). Just be aware that jumping and crouching might break some of the levels.

I know this thread is a bit old, but I'd just like to point out that Steam by default has DOSBox at a setting that makes Doom (and possibly any other DOS game) lag like that.

All you have to do to fix it is go to the ultimate doom folder, go to "base", then open either ultimate.conf, ultimatem.conf, or both in Notepad. Under [SDL], find "output=surface". Change "surface" to either "opengl" or "ddraw" and your set. No more lag!

Feel free to still use a source port if you want, but at least now you know you can play vanilla doom lag free through DOSBox.

Thanks gamephreak5 for the fix. Now Doom is running smoothly.

Just want to thank gamephreak5 for his good suggestions and they worked - Ultimate Doom is now running perfectly. I used the "opengl" line in both docs. Good fix for a great game.

Or you could download Zdoom (http://zdoom.org/News) which is wonderful in every way and just simple to install.

Now I'm feeling like an advertisement boy or something.

But still, from gamer to gamer, Zdoom provides the best experience when playing the old Doom titles. It removes the framerate lag, adds decent fullscreen, makes the whole game a lot more smoother, and gives you plenty of settings to mess with. Plus the ingame console for le cheets.

Ultimate lag in Doom? :p

[eyezex]

Yes indeed an old thread, and another thanks huge thanks goes out to gamephreak5 for his fix. i would just like to add that ddraw and opengl were not working for me either and i remembered that i was running One Whole Unit Blood on overlay So i tried that with Ultimate Doom and it worked like a charm. Hope that helps if anyone else has the same problem.
Peace

I'd also like to point out that if you want the game to look and play like on an original DOS computer, check out Chocolate Doom. http://www.chocolate-doom.org
It intentionally recreates the experience of playing DOS Doom, but it's a modern Windows program so you don't need DosBox. They just programmed the setup app to look like DOS, it's really all native Windows, so no slowdown from emulation or the Steam overlay.
