I tested the 4.0.0 drivers for the PCX1. Damn the performance drop is significant compared to the 4.1.2 in Direct3D in all games! The drivers certainly improved over time. With the 4.0.0 I could finally get Motoracer (demo) running without problems, but the framerate suffered. A patch was released for Motoracer retail, but I only got the Mystique enhanced version of the game and it doesn't work with that version.

Hellbender and MTM trial still didn't work properly with the 4.0.0 drivers. What is curious though is that I can't find any information on Google Groups about people really complaining about these two games in late 96/early 97. They were prime test candidates for D3D games. Only thing I find is that they run slow, which makes me think that PowerVR never bothered to fix these games, but just turned off acceleration on the PCX1 in the application settings.

Die Hard Triology still don't want to run in D3D mode. I have no clue what is going on there, as the readme states support for the PCX1.

that's interesting...I am thinking it's about the other way round. older drivers are better for my PCX1.
I am currently using the Apocalypse3d driver from this CD http://vogonsdrivers.com/getfile.php?fileid=995&menustate=0

Think that depends on each game, some will run better, some actually worse, and some will run correct. Also the host card can have alot to say on the performace you get, see https://gona.mactar.hu/DOS_TESTS/ where Gona gets huge differences in frame rate Tomb Raider

Also if you need drivers, I've made a compilation with all drivers that I was able to acquire:

I used that collection-drivers before, but the driver on Apocalypse-CD v5 is different from your collection.
It has also a very different install process. Please check that. The driver from V5 is 11/1997! 4.0.2.x?
I think also the framerate on Motoracer1 seems to be much better!

Another idea that comes to my mind is, if there exists a sgl-wrapper. could this thing perhaps be used the other way to improve compatibility for the original card and d3d games? just an stupid idea...

You're right, the driver on this CD is 4.0.2, which is not included. What about 4.1.1 or 4.1.2 for the Apocalyse 3D (PCX1) in that compilation, do they also cause lower framerates?

I think so, I should prove this on fraps, but on forsaken and motoracer1 it is very obvious.

it's not only the date, the filesize of the drivers is also different from any other "reference" release.

I have a solution for POD 😀 You have to install the pod21pvr update TWICE! then he generates a podpvr and everything is fine 😀 nhlpowerplay98 is stuttering on the 4.0.2 drivers but fifa98 is fine. I stick to these 4.0.2 drivers.

If someone will test out other textures for tombraider2, then please check these:

https://core-design.com/FTP/TR2_Alpha_Mod_Part_1.zip
https://core-design.com/FTP/TR2_Alpha_Mod_Part_2.zip
https://core-design.com/FTP/TR2_Alpha_Mod_Part_3.zip

They do work with PVR-Renderer 😀 . Decide for ourself if they are better than the original ones.

Far from being perfect, but they work on PCX1. Copy the *.wad file in the directory and then use the launcher or a batch file. Hexen has the worst compatibility. Menu is broken, Hud is broken (on all), reflections/lights are too bright. But hey...it works! Don't know how to improve with the opengl32.ini or if the is another better version of the opengl32.dll.

so would the pcx2 fair better in a 64bit pci slot maybe. can it even take adavantage ? i can see the slight boost of a maybe a bx system at 133fsb because of the overclocked pci bus but your still stuck with a pentium 3 . then again doubt you can expect much more moving to a pentium 4.

in bx system pci bus doesn't overclock it has proper divider, its the AGP bus that overclocks to 89mhz
in a true 66mhz pci slot that was attached to like a PCI-X 133 slot the card wouldn't run becasue its not 3.3v keyed. Its keyed for 5vonly. It wouldn't even be insert able in such a slot.
the card though will get better FPS on faster CPUs though as it scales.

No, 64bit PCI requires that extended connector.
Gona just tried 66 MHz PCI on Apocalypse 3Dx and it did not work either.

oh yea thats right for some reason i thought the pci bus was also overclocked my bad well unless you have pci divider control but correct my bad. and thats right about 5v issue damn to much dreaming in my head.
