On the website part of the performance of the program, where you can change the 'Number of frames per second for graphics' and the 'Percentage of CPU time used for graphics', if I change the frames per second from 10 to 30, will this affect the speed of the calculations since I haven't changed the percentage of CPU time? Any help would be appreciated. Thanks ID: 48633 · Rating: 0 · rate: / Reply Quote

Whether it slows them by any significant amount I don't know... HTH Danny ID: 48637 · Rating: 0 · rate: / Reply Quote
