Re: Matrox G400/G450 Quake III Performance

It's a 256MB Parhelia. Its clocked at 250MHz. The 128MB Parhelia is clocked at 207MHz. I ran some benchmarks on the 2 Parhelias and the 256MB one is much faster, sometimes as much as 40%. I'm not sure why as its only clocked 20% higher. Possibly a respin of the GPU silicon? Parhelia was rather …

Re: Matrox G400/G450 Quake III Performance

I ran some more benchmarks on the G400 with high textures in quake3. To see if the slowdown bug is caused by the OS or hardware. All the tests were done with the highest textures (r_picmip=0), 32bit colour, 32bit textures. I ran them all on the same P3 I did the other windows 98 tests on. P3@1GHz in …

Re: Matrox G400/G450 Quake III Performance

Ok. I did some testing on Windows 98 with a P3@1GHz, 256MB at PC133 CL2 and a G400Max. The TurboGL is only supported on Win9x so my earlier tests were all with the full ICD. Matrox recommends an AGP aperture size of 256MB but there is no option for it in my boards BIOS and powerstrip says its set …

Re: Matrox G400/G450 Quake III Performance

After a bit of trial and error I got the 1.3 version of the TurboGL to work on the G450. I had to install the driver off the G450 driver CD that I got from the Vogons driver library. It's version 603, date is 2000/08/17. The performance improvement was small though, went from 63 fps at 640x480x32 to …

Re: Matrox G400/G450 Quake III Performance

I recently did some benchmarking on my G400Maxx to compare it to my Matrox Parhelia and figured I would post it here. I benched all the G400 drivers I could find for windows xp. I'll do the same thing with windows 98 in my 1GHz p3 system too, once I'm done with the Parhelia. Here is the link: …
