HL -OF , G400 , OPEN GL and Via chipsets

[biors]

I used to play half life with the older turbo GL and it worked great, now i upgrade with Opposing Forces and my old turbo GL crashed .
I tried the the new driver 5.52 and the new turbo gl but the results are the same.
My config is :
FIC PA 2013 (via chipset)
K6-2-400
64 MO SDRAM
G400 DH
PD 5.41
direct x 6
the only thing i can do is to play HL in D3D mode but the frame rate is very slow ie 10-18 fps.
any one else has the same problem , what can i do to increase the frame rate.
thanks for advises .

i've got this very slow framerates in d3d, too. i think it's the hl-update since 1.0.13 or 1.0.15 OR the latest matrox-drivers (5.41 and 5.52). i will try 5.30+tgl and hl-retail-version. also tgl isn't working for me with 5.52, so i use the icd which is a bit faster than d3d, but 5.30+tgl was fastest i think.
