laggy performance

[luxirom]

hi!

i just bought your game and installed it on my G5 (dual 2Ghz)

the graphics-card is a ATI Radeon 9600 Pro with 64MB VRAM.

I know the VRAM is not much, so i turned off ALL features and used lowest setting possible. (troubleshooting)

the game looks just awkward of course. BUT the laggy parts remain!
it's not everywhere on the map, but mostly in bigger areas with 2 or 3 dogs patrolling. (in the area where you can get to chemlab, incinerator, etc.).

and it REALLY lags as hell. since i turned off totally every graphics feature and run on 640*480, i think there is really something wrong with the mac port of this game?

Other Sys-Specs:
RAM: 1.5 GB
OS 10.5


I then tried to run it on my MacBook Pro (2.2GHz Core 2 Duo, 2GB RAM and 128 MB GeForce 8600M GT).

Problem remains even on this Machine: turning around the Character kills framerate to a unusable state...

how can i improve this problem? or is there a way to get the PC-Version legally to run it on XP on my MAC Book Pro? Probably the PC Version is more fluent?

Many thanks for hints and help!
