This is just plain bizarre. I see several posts about frame rate loss, and yet I have 3 different systems here ranging from a 550Mhz P3 to a 1.8Ghz P4 Northwood and 3 different video cards (NVidia Gf2 64MB GTS Pro, ATI Radeon, and ATI Radeon 9500) and for the life of me I cannot duplicate the frame rate loss.
Indeed, my 1.8Ghz ATI Radeon 8500 based system actuall gained a few FPS from 1.08 to 1.09.
The only thing I can speculate on as to why some would see a loss and others would not would be the Internet connection itself. I do have faster than normal access to the Internet than most would.
To those having frame rate loss, I think it might be interesting to see what type of Internet connection you have. Whether of not you are using a USB based modem, winmodem, or whatever type of connection information you can post might help. If you have DSL or cable, please state the up and down speeds of the connection as well.
Are you NAT based? Do you go through a proxy? Are the effects different when you disable or enable your personal firewall?
Those that are not having any FPS degradation, please post your data too.
Maybe we can find a coorelation between these. I am really reaching here, but there has to be something consistent between those who claim a loss in FPS versus those who have no degradation of FPS.
