Sorry to ask for such low tech help but I am frustrated! I have an IBM Thinkpad with the ATI Radeon 7500 graphics, 1.69 GHz,1GB RAM and oodles of HD but when I run my old GTR or F1 Challenge games (which are within the laptop specs)there are intermittent stutters or hesitations. I have tried adjusting the graphics card for preformance, reducing the game graphic details, closed all active MS programmes and stay off line with no apparent improvement. The hesitations are less than a second 2-3 times per lap but very annoying. It does not get worse if I increase the number of cars and the gameruns really well. Can anyone suggest where the problem may be? Many thanks for any help offered.
