Bought the German Version of Lands of Lore 2 as well and tested that, but got the same result. Applied Patch 1.3 which adds hardware acceleration in theory but its greyed out. Then copied in the Glide2x.ovl which does enable hardware acceleration.
However when I enable it, I get the same bug I showed in the video shown in the initial post.

I also found another curiosity: If you use software mode instead (high res) which is then 640x400, then the colors on a TFT or capture card will be broken. I had the same thing with Toonstruck (also 640x400). On a CRT it shows fine, but anything but a CRT and you get some flickering or bad colors. Not sure if this is also related to the Voodoo 3.

This issue is not present on the extron rgb-hdmi 300 a and an AVerMedia GC553, played on OG hardware (voodoo 2 + matrox G200)

Could you try this without the extron? The extron 109xi fixes it for me. That said, I also have found a workaround to fix this with software: I used Unirefresh to redefine the 640x400 resolution and set it to 75Hz. That way it works.
Would still be cool to know whether this works fine on other cards.

The 3dfx issue is ofc not affected by this.

I can try in the next days (work is killing me) i'm also modding the case for the 97 PC with the hardware for lands of lore 2.

I don't have a voodoo 3 but I have this running on both my Voodoo 2 and Voodoo 5 with the last patch and the latest official 3dfx drivers for Win98SE and both do not have this issue.

Interesting. I had this in DOS though, I am not sure if the game overwrites any of that. The voodoo 2 shouldn't be doing anything here in this software modus. You use both in the same system? Or does the V2 work together with another card which is doing fine here?

Also I guess you are talking about the color thing. The issue with GLIDE can't be tested in Windows as in Windows hardware acceleration is not supported.

With the latest patch for LOL2 it supports hardware in Windows. Im talking about glide.

Oh, interesting. Did you copy over anything into the Lands of Lore 2 directory? Or did it identify your Voodoo 5 right away (afaik the Voodoo 2 should work fine) - or do you have both in the same system?

These are old installs and I can't recall if I did anything special manually. These are 2 separate systems. The Voodoo 2 is in a system with another 3d card, and the Voodoo 5 is the standalone card in that system.

Thanks.
From how I understand it, the Patch 1.3 adds 3D Hardware acceleration. However:
DOS Received only 3dfx acceleration, no other cards are supported
Windows only received Drirect 3D acceleration. No 3dfx acceleration.

And I think some effects are exclusive to 3dfx acceleration which is DOS only. But I am going to check tomorrow if I can see any obvious differences. Haven't tested the windows version much.

Oh sorry I didnt realize that, sorry for confusing the issue. I guess I'm not sure what API its using.

I just tried this on my P133 DOS machine with a Voodoo Banshee and it didn't have this issue. There is a caching problem but the engine itself doesn't have this problem.

Looks like a bad video memory chip. This can be checked with test VMT

you can use the DOS version - VMT CE

Thank you. I tested, but no issues found

It's likely that only the Voodoo 3,4,5 have the issue.

I did a few screenshots as comparison.
But generally it is as I mentioned before:
Without Hardware acceleration in DOS, it switches to 640x400 and it looks pretty ugly. (ignore the wrong crop in this case, capture card had not been adjusted)

DOS offers support for Glide only as hardware acceleration. In that mode it switches to 640x480 and it looks pretty good. Note that it uses the full 640x480 pixels. Ofc this mode is broken on my machine.

On Windows it can be used by any card with hardware accleration (direct3d) It switches to 640x480 but it only uses 640x400. On these screenshots for 640x480 its pixel doubled, you can count 800 vertical pixels =400.
This is the option the game then starts with, which is 4x4x4x4 deactivated

If you activate 4x4x4x4, the water becomes more transparent but the glowing aura goes away:

So the graphics for Windows Hardware acceleration and DOS Hardware acceleration look very similar. However Windows only effectively offers 640x400, which is a squished 640x480 picture.

I repair voodoo 3/4 for fun and often see exactly this picture
