4.6/1.6 — Major Drop in FPS — Still Problems
Please excuse this somewhat rambling post. I just finished a couple of hours of uninstalling/reinstalling different versions of Max/Jitter and going through a ton of debugging, so I don’t claim complete coherency.
XP, Dell 6400 laptop. Core2Duo 2.16. 2Gb RAM. Radeon x1400. QuickTime 6.5.1. Java 5.x.
Last week I reported a major drop in FPS when upgrading from Max 4.5.x / Jitter 1.5.x to 4.6.2 / 1.6.2.
My patches are all QT-based. No OpenGL. No slabs.
More details at this url, but I’m recounting the highlights in this new post:
FPS to remain the same in the upgraded versions of Max/Jitter compared to older versions.
When I reverted to 4.5.x/1.5.x, my problems disappeared.
Jeremy suggested it might be related to a change in the default behavior of jit.qt.movie and ‘highquality’.
Was not the case — the highquality setting made no difference.
I have spent alot of time tearing my patches apart, but nothing helps the problem.
I initially suspected a problem with addressing both cores, but Task Manager indicated both in use.
Unless I’m making a mistake, the following Messages to Jitter work in 4.5.x/1.5.x but *have no effect* in 4.6.2/1.6.2 on my machine:
Other messages, such as ‘about’, do work.
Jitter messages ‘parallel’ and ‘parallel threads’ work in 4.6.2/1.6.2
Any thoughts or suggestions? I don’t think it’s worth posting patches, because just about any qt-based patch I’ve tried experiences the problem.
I’m especially concerned about the messages to Jitter issue. With the significant drop in FPS and the processor-related messages not working on my machine, it seems like something’s up…
