Not known. Best just try out the demo. You will need either DirectX 9 or OpenGL compatible drivers for the card. 16MB may be a bit small for running the TRX textures, although "managed textures" mode in Glidos v1.25 might help.

I'm able to run Tomb Raider with Glidos 1.35 under Windows XP, but textures are corrupted. They look like a bunch of big triangles. I don't use TRX textures, only the original ones. I have DirectX 9 compatible drivers and "Managed textures" switched on.
So 16MB is not enough? Or the graphics card isn't able to handle this?

Try with managed textures off.

Try the OpenGL setting, providing you can find drivers for the card.

Post some screen shots and I might be able to tell what is happening (saved in jpg format, not bmp).

The original textures are corrupted, no matter what settings I use. They look like in the screenshot below.
I tried to use enhanced textures and they work well, except close distances, but mipmapping has to be switched off. When it's switched on, the textures look like the corrupted original ones.

I have some idea what is causing that, especially as the distant textures look right.

From what you say, OpenGL at least works at reasonable speed for you, although you get corruptions. If so, there is one more thing worth trying. Grab the old version of OpenGLide from the Red Baron page of the Glidos web site. Put the file Glide2x.dll in your Glidos folder (probably c:\Program Files\Glidos) in place of the existing version of that file. That may help.

There may be thing I can try that will help.

I replaced the file Glide2x.dll with the older version. I can't see any difference with original Tomb Raider textures, you can see first screenshot. When I switch to any of the enhanced textures, they don't show up. Everything is grey, not only in 3D as you can see in the second screenshot, but also the passport in the main menu and the background picture there.

Not willing to sound pessimistic, but the Vanta is a low-end TNT card. I'm not even certain it supports OpenGL 1.3+ (and it definitely won't work with psVoodoo). At least make sure you're using the right ForceWare version for your chipset. The 71.89 release was the last one compatible with the TNT line.

Kaminari,
yes, I'm aware the Vanta is an old and not too powerful card. I was afraid, if it is able to handle Glidos requirements. That was the reason for my original question. I was able to use ForceWare 71.84 under Windows ME. Unfortunately, under Windows XP none of 7x.xx driver versions is able to detect my Vanta, though the Vanta should be supported. So I have to use version 66.93 under XP. This version should support DirectX 9.0c and OpenGL 1.5. If the Vanta supports this as well, that's a question. I haven't been able to find any reliable information on that.

According to http://en.wikipedia.org/wiki/Comparison_of_NV … rocessing_Units Vanta cards should support DirectX 6 and OpenGL 1.1. Is this sufficient for Glidos or not?
Interesting thing is, that enhanced textures work better then the original ones.

Ah yes, I forgot: that old OpenGLide from the Red Baron page doesn't support the 32bit textures used in TRX. That's why you are getting all greys. Anyway, the results suggest that your problems aren't to do with OpenGL version.

I have some idea what is going on. It does look to be a fault in the driver, but maybe something that can be worked around. I think I can make a version that maps the textures right, but will loose their perspective. That will make them distort as you get close to them.

You may have told me this, but I can't see it in the thread, what happens when you select - from the Glidos "Adust" dialog - "Direct3D (psVoodoo)"?

When I select the Direct3D mode, textures seem to be correct, but some objects become transparent. You can see it in the screenshots. First one is with the original textures, the second one with Antonijadis's textures.

Thanks for those. The D3D case looks like a depth buffer problem, which figures. Could you post your psVoodoo.log.

Don't give up yet. I have some ideas to try out. I'll get back to you.

Thank you, Paul. Here is my psVoodoo.log.

Yes, the log shows creation of the 24bit depth buffer failing. Here's a version that falls back to 16bit. 16bit isn't enough really. You get serrated edges between object, but its better than no depth buffer.

I also have some ideas for the problems with OpenGLide which I will try out.

Here are two altered versions of OpenGLide. v9b10x, in effect has perspective turned off for texture mapping. That will make close textures distort, but may avoid the specific problems the Vantra is showing.

v9b10y is a wild guess at what might be wrong in the Vantra drivers. Who knows. We might be lucky. There's some possibility that both versions will behave identically on the Vantra, but that in itself would tell us something.

Thank you, Paul. With your last psVoodoo driver, there are nearly no problems. The wrong transparency is removed. Only when I use Antonijadis's textures, some objects, including Lara, are not displayed correctly.
With the v9b10x OpenGlide driver, everything is nearly perfect as well, both the original textures, and the enhanced ones. It's little bit worse with the v9b10y version, which produces more corruptions then the v9b10x in my opinion, but it's still much better then before.
Thank you once again for your help.

When using psVoodoo, do you have managed textures selected?

Any chance you could do a screen shot for OpenGlide v9b10x for the same view as you gave for the y variant?

I have Managed textures not selected. Here are screenshots for both versions. I don't know, why Lara is missing in the x-version one. She was definitely there, when I was taking the screenshot. Perhaps you will know.

With psVoodoo you should be better off with managed textures selected, especially for Antonijadis's pack
