This series of tests was run by spawning in a map while not moving at all and always facing the same direction, while slowing increasing the number of loops. CFS generally seemed a lot smoother as the load increased, while SD broke down to a highly unstable fps count that fluctuated massively around the third loop. Seems like I will stick to CFS for gaming now. Below you will find the results of my test with the average number of FPS= =2E CFS | SD UT2004 + 0 loops | 200 FPS UT2004 + 0 loops | 190 FPS UT2004 + 1 loops | 195 FPS UT2004 + 1 loops | 190 FPS UT2004 + 2 loops | 190 FPS UT2004 + 2 loops | 190 FPS UT2004 + 3 loops | 189 FPS UT2004 + 3 loops | 136 FPS UT2004 + 4 loops | 150 FPS UT2004 + 4 loops | 137 FPS UT2004 + 5 loops | 145 FPS UT2004 + 5 loops | 136 FPS UT2004 + 6 loops | 145 FPS UT2004 + 6 loops | 105 FPS UT2004 + 7 loops | 118 FPS UT2004 + 7 loops | 104 FPS UT2004 + 8 loops | 97 FPS UT2004 + 8 loops | 104 FPS UT2004 + 9 loops | 94 FPS UT2004 + 9 loops | 89 FPS UT2004 + 10 loops | 92 FPS UT2004 + 10 loops | 91 FPS --=20 Kenneth Prugh --------------enig42DDD0AB56AFD57E100CAAB0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGrlcQ0PM4px2/kjgRAiYJAJ0c72onj6fVfGQXar2zeyQ/+SbZhQCdGE1I fcwlppIzcldrF8JtuyLr0J8= =U5zV -----END PGP SIGNATURE----- --------------enig42DDD0AB56AFD57E100CAAB0--
