Contrasting performance
Posted: Thu Dec 29, 2011 1:47 pm
Since I installed the update 4 I noticed some strange performance degradation between Update 3 and 4 that can occur under certain circumstances, of course the system is actually much faster than before (even compared to the Update 3, and this doesn't seems only a placebo effect!) but using AmigaOS a little bit (even browsing the web for 10 minutes) and then launching some 3D games (such Quake 3 or even ADoom) i can note some general speed issues that instead are not visible at all if i launch that games after a reboot without opening anythings else before
For example if i reboot my Amiga and then browsing the web with MUI OWB, then --> start Quake 3 i get:
At 640*480 i get 12.3 FPS
That are the Quake 3 settings i use:
At 640*480 i get 20.3 FPS
8 FPS of difference !
(note that i use a special Quake 3 version from m3x not yet released)
I note the same problems with ADoom 1.4 taked from Aminet, so it's not a Quake 3 fault, or it seems not ...
Checking the Update 4 archive i note only that new version of Picasso96API.library (version 2.359), did you know if that strange problem can be caused by that updated library ?
I did all that test on my Sam440ep Flex 800 Mhz with Radeon 9250

Convesely if i reboot my Amiga and then start Quake 3 only (and with the same Quake 3 settings for the TimeDemo) i get:GL extension: ON
Video mode: 640x480
Color Depth: 32bit
Fullscreen: ON
Lighting: Lightmap
Geometric: Detail HIGH
Texture Detail: Max level
Texture Quality: 32bit
Texture Filter: Trilinear
