Hello
I have a NEC PCX1 card, and i want tra to test it.
I tried with Tomb raider with PCX1 patch under DOS, but this resulted a blankscreen for me.
With windows95 the ultimaterace working, but ÍMonster truck madness not ( i try with rendition setting and card, that worked for me)

Please help to find it out, what is the problem.
My rig is Socket5 config with dr.bios and pentium overdrive 166

Look for some DOS games in this list: Re: The Ultimate 3D Accelerated Supported Games List (Early proprietary APIs - NO 3DFX/GLIDE)

Thank you, i know this thread, but my main problem is only 1 work from 3 powervr games i try.
I dont know what is the problem, maybe just little error.
I have standard DOS 6.0 install for Tomb raider.
P166+s5 intel/p200+s7 rig tried
I make fakecd for emulate cd in my test rig the TR CD,
Tried other version of Tom raider, all of them working: standard sw, s3d, matrox mystiq, 3dfx with voodoo, Rendition v2200 with v2 fix.
But with pcx1 card installed to rig, and started Tomb raider with pcx1 exe, screen goes blank, or last time i see the attached error message.
With windows 95 i tried ultimate race pro what as i know powervr only game, that worked for me.
The i tried Monster truck madness 2, thats worked with graphics option set up tosoftware rendering, and rendition with rendition card, but with set up set to powervr, there are blank screen to.
I see every hardware has separate irq.
Is any rules, which pci slot can i plug my pcx1 card?
Or with which vga card can it working, and with which card work it faulty?
Maybe with bios settings are some problem?

TR1 is possibly one of the worst ways to test a card. It is unnecessarily complicated.
Simpler: use demos from Videologic Apocalypse CD with drivers provided on the same CD. You can't go wrong that way.
That's what your card is btw, a Videologic Apocalypse 3D. Nec just made it for Videologic.
