I have some problem about my home PC. It has configuration of P4 1.7 Ghz, Intel Original 845 PT card, 40 GB hard disk drive, 256 MB DDR [ 266 Mhz ] ram, OS is Win 98 SE Direct X 8.1. I recently tried to upgrade my Graphics card from RIVA TNT2 M64 [ Perks make ] to Geforce 2 MX 400 [ Lancer make ]. My problem is that the new card is not giving full performance as given in your magzine. I checked with 3D marks SE demo version. It gets only 950 marks at 1024 x 768 , 32 bit colors. Where as my old TNT2 card gets 850 marks at 1024 x 768, 32 bit colors. Geforce 2 MX 400 should get 2700 3D marks. Please tell me what is the problem. I checked it on Athlon 1600+ PC, MSI VIA Kt 400, 256 MB DDR 266 Mhz, 40 GH 7200 RPM Hard Disk but the marks remains the same.
