Sorry I don't know. W2K certainly isn't a problem. The Matrox is a bit of an unknown.

Hmm, it's interesting: I have exactly the same problem with my ATI Radeon 9000 Pro card. But as far as I remember, I always had that (with different cards and settings), so I always thought it's normal... 🙄

My X800 xt shows a bit more delay when pressing ESC than my old GF3ti500, although its no more than a second. I'm about to completly restructure the threading in Glidos. That might help.

This seems to be because ATI's implementation of ReadPixels is really slow. If you add "DisableLfbReads: Yes" to the TR section of glidos.ini it speeds up, but you don't see the dimmed screem shot behind the ring menu.

Hey Paul..

That "DisableLfbReads: Yes" trick did it for me. Now the game is running smoothly on my machine with a Matrox Parhelia..

thanks for the great job you are doing helping us to be able to play one of the best games ever made the TR1!!!!!!

Many thanks Paul! I tried it, and it worked. 😎 The blank screen is not a problem: if I want it back, I just simply change that option... And it's still very fast, anyway. By the way, is there a list somewhere about the possible options what You can set in Glidos.ini? Some of them may be useful sometimes...

And my problem also exists: the game lags in about every 10 seconds. It seems that it skips frames, but it stops for a millisecond in about every 10 seconds. It's very annoying, so if someone has tips, hit me with them please. Thanks! 😀

I agree with Sys that a list of available options should be made available so that those of us that can use them will know what they are for and what effects they produce.
For instance, I am running Glidos 1.29 and have two additions to my Glidos.ini file-
Mp3BackroundSounds: Yes
RedbookEmulation: Yes
I have no idea where these additions came from or what they do.
I also had an addition in earlier versions of "EnableMMX" and got no answer as to what if anything it does.
Thanks for doing such a great job Paul and keep up the good work.

Yes I must explain the options. I'll try to get around to that soon.

The 10 second glitch: sounds like something running in the background - maybe a motherboard monitor (tempature fan speed, that sort of thing).

In the meantime... 😀

1. Mp3BackgroundSounds: option to play optional MP3 tracks in TR instead of Redbook (CD) tracks.
2. RedbookEmulation: enables or disables the built-in CD support in Glidos (it's useful to disable it if you're using an MSCDEX driver replacement like SAPUCDEX).
3. EnableMMX: enables MMX instructions (CPU optimization). I believe this option is located in OpenGlide.ini, not Glidos.ini.

Paul, I have no idea about what was the problem with the previous version, but I've just installed and tried version 1.30. And the result: TR1 runs smoother and faster than ever with no lags at all! Thank You! 😀

I also increased the texture memory size and the frame buffer size to the maximum in OpenGLid.ini, and I also set the wrapper priority to 3..but I don't know if this cured my previous annoying problem (since TR1 was smooth earlier), or the new version of GliDOS. Anyway I know, there wasn't anything running in the background what could disturb GliDOS (I had this problem earlier though, with the ATI TaskBar Utility, and that result was different). All in all, it's perfect again, and that's point... 😎 I haven't tested TR1Gold, but I'm sure it works nicely too...

Great! In v1.30, I've changed the way threading is used. This was in response to a problems with Descent II running on ATI cards (I have an ATI card now). I didn't realise the problem affected TR also.
