Yeah I can go ahead and do memtest when I get back from work. The machine officially only had a 64mb chip sold but unofficially, I-O data sold a 128mb chip to go in it. Hard to find nowadays. EDIT: I am still running memtest, but it has done 1 pass already with no errors being found, which …

I am running speed sys now on both systems, and getting a .txt file report as well. I will update this post when it is finished. EDIT: I have ran the program twice on my problematic machine (C1XS) and one full test on my functional machine (C1XF). I have attached the reports in this edit, and it …

Yeah I am really at a loss right now. I might circle back and do more testing on my functional machine just to make sure this is definitely an isolated issue. EDIT: I can confirm that my functional machine has no issues with stuttering in either doom or Duke 3d AE.

I see. Well, the CPUID information would be useful if you can get it. I don't have much experience with it, but my understanding is that Fastvid is specifically intended to compensate for shortcomings in certain revisions of Pentium II processors, and that these problems would otherwise be …

I am having problems when I restart in DOS. In windows 98, running DOS games shows no stutter whatsoever, which is what is throwing me for a loop. I am referring to three different things here: a) Running DOS games while Windows 98 is running. b) Running DOS games by shutting down Windows 98 with " …

So, this is a laptop without any discrete video card, right? I have a Sony Picturebook C1XS that is experinecing intermittent slow downs in real mode DOS games, yet it is not having the same problem when run in MS-DOS mode from windows 98. For example, I can play Doom fron within windows 98 with no …

I do not use a usb keyboard. I went to look in the bios, and to be honest it is super basic with only an auto throttle control or none. I went ahead and reset the bios to default values, making sure no throttle control, and still the same problems. I am starting to wonder if it is somehow the …

So I went ahead and swapped hard drives, with still the same problems, which leads me to believe it is a hardware issue. Then, I tested it by taking out the memory I had put in it recently, but still the same. This may sound like a dumb question, but could it be an issue with my display cable to the …

Additionally, I tested the games out on a separate but identical machine with no issues. Completely identical? It might be useful to swap components one by one and see if you can trace the problem that way. The video card would be a good start, or possibly the memory modules. I might be inclined to …

I tried running it from safe mode command prompt only so as to have a barebones dos startup. Since I was testing it using Duke 3D, I intialized only the sound drivers. I started up the game and still had the same problem. When I went to reboot normally, it says my HIMEM.sys is missing, yet I looked …

You're welcome. I think it is just in DOS that the 16-bit is not working. I'm not even sure if there are any DOS games that directly support the Yamaha chips so it probably doesn't even matter. The only thing I can think of that might is AIL / Miles Sound System which would make it a problem but …

Did you run setupds /s Or just setupds If the second, then the card is not initialized. When first installing the card, I've never ran "setupds /s" before actually running setupds, and it has always worked for me just fine (on compatible motherboards, of course). I add "setupds /s" in autoexec.bat …
