Re: A glide wrapper for DOS programs

Thanks DoomGazer, I have the abandonware version of Blood, and I use it IN exactly the same way you wrote it. :happy: The slowdown problem (slowmotion) comes out under XP (and 2k) due to the following: There are two threads, one for the DOS program, and one for the DX-rendering code. While the …

Re: A glide wrapper for DOS programs

Craig! It's needless to try with newer drivers. Weird colour scheme is the fault of the wrapper, not your driver (I ment this thing under texture bug). Unfortunately, I didn't managed to get the files from the dvd I've mentioned. :sad: Ice, thank you for offering your help! As for the glide version …

Re: A glide wrapper for DOS programs

I'm working on a new version. I've tried it with Screamer rally (thanks Craig for the stuff!), and it worked under w98 as well as xp. There is, however, a texture-bug coming out with w98 in 1.22b, which is due to a designing mistake in the communication. I can't get Screamer2 to run because of some …

Re: A glide wrapper for DOS programs

Uhh, those are very very large values. Ok, I've just reloaded a new 1.22b on my page :happyhappy: , try that. I've studied the code, and there was a point where I set the dos thread priority to high. It didn't cause any problem on my hyperthreading p4, but when I set the affinity to one processor, …

Re: A glide wrapper for DOS programs

I was searching on the web, and found the following info about ATI + w buffer: Radeon 9500+ cards no longer supports w buffer and 32 bit z buffer. :shocked: :dead: I was hoping those are disabled in driver level but somewhere else I read that w buffer support is absent in Rx3x0 GPUs. I also saw that …

Re: A glide wrapper for DOS programs

Tried in in NFS2SE: pretty much the same unfortunately. Somehow I'm not surprised. There is a thing I haven't talked about so far. When I got my new computer and tried my wrapper with my GeForce, I noticed that w buffering doesn't work with it. I quickly started finding out what could the problem …

Re: A glide wrapper for DOS programs

OK Craig, I'll send you my address, thanks for your help in anticipation! (I have a DVD drive). Ableeker, what do you mean under test partition? I'm going to compile a logging version of the glide2x.dll for the new version to make problems be detected easier. Barev, this resetting thing sounds as if …

Re: A glide wrapper for DOS programs

DoomGaZer, yes, I think it's a problem has something to do with win95 compatibility, altough setting win95 compatibility for SW 3dfx doesn't change anything for me (to be quite frank, I don't know what EXACTLY those compatibility modes does). It's possible that the solution is very simple, but I …

Re: A glide wrapper for DOS programs

Hi Zeckensack!! Thank you very much for offering your help!! :cool: :cool: I think it's a good idea to help each other, I think I will contact you. Yes, I handle grHint(GR_HINT_STW_DIFF_TMU0), I don't think there is a bug there. D3D can accept 1,2,3 and 4D texture coordinates, but in practice it …

Re: A glide wrapper for DOS programs

I think I shouldn't release the "new" version, it would have no point if it still had problems with w-buffer on ATIs. I've put a test version to http://dege.fw.hu/dgvoodoo_test.zip instead. This writes a log file about depth buffer operations. I don't know if this version fixes all your problems, …

Re: A glide wrapper for DOS programs

CraigG, thanks the info!! I hoped this will help. I've fixed the perspective problem, but I'm afraid that's not all of your problem. Probably it would behave as 1.20. I mentioned I was going to fix the palette problem in SW before releasing the fixed version. Well, it's much harder than I thought. …

Re: A glide wrapper for DOS programs

Ok. I'm going to fix that palette-thing in SW then re-release 1.21. According to the docs, texture perspective has to be enabled when w-buffering is used (missing polygons are due to lack of it). This is a really big bug. However I still don't know why w-buffering doesn't work on ATI.

Re: A glide wrapper for DOS programs

Yes, another bug I've found: other people also talked to me about swimming textures. I've realized that I always keep texture perspective disabled in 1.21. Probably I did it for debugging purposes or whatever and forgot to recover. It's interesting that this problem doesn't come out on nVidia cards …

Re: A glide wrapper for DOS programs

Well, the bug is in dgVoodoo. Once I downloaded and tried SW with this wrapper, and it worked when I used the built-in VESA support. Now I've downloaded and tried it again, and it worked in no way. When glide is active the wrapper keep a fake VESA driver installed to prevent DOS programs from …

Re: A glide wrapper for DOS programs

DoomGazer: dgVoodoo never writes out textures to the HD. It's the game itself that converts textures to a glide-compatible format in a way it writes them out as .3DF files and read them in by the wrapper. Have you tried to make SW convert textures in memory? You can do that setting BUILD_ …

Re: A glide wrapper for DOS programs

About the point of view problem: even the glide version of TR1 tries to set mode 640x480 via VESA at startup. If it fails, TR thinks it will fail for glide too, for some reason. Anyhow, it's a messy thing: coordinate transformations go to 320x200 while clipping is applied to the 640x480 extent. If I …
