Problem with multiple projectors and scenes, drastic drop of framerate with each new display.
-
I installed a clean Windows. I use isadora to play movies on multiscreen with a ati Radeon 6870 Eyefinity 6. Until new installation, everything was OK. I was able to play 6 720*576 movies (photo jpeg 60%) linked to 6 projectors and 6 scenes. Now with the new install, isadora is laggy and the better I have is 7 fps. I tryed everything I could think of (old ATI Drivers, change of GPU, chipset drivers update), with no luck. Could you please help me to get back performance ?

I tried to use movie player direct to play 6 movies. I work very well. This time, I can have 201cycles, framerate is 50 fps (target is 60). So, it is not a problem with Hard Drive. Use of Ram and processor is also better (see screen captures below). Benoit

Dear webmammuth,
When you say "new install" what do you mean? Please give the exact version number.

Dear webmammuth,
I just created a simple patch recreating your situation: 6 720x576 Photo JPEG movies (compressed using QuickTime Player) playing to six separate stages.
I'm getting the full 22fps with 1.3.0f24 and 25fps with 1.3.0f32 (target frame rate = 25fps.)
This is on my Mac Book Pro running Windows 7 natively -- Intel 2.2 GHz i7 pfocessor with an AMD Radeon 6750M.
So the performance is a bit better on the new pre-release (available here) but certainly not 7fps. Could anything else have changed?
Best Wishes,

Yes, it's true, the links for f32 Windows are broken.. I've been trying for a while and assumed that only the MAC version was ready!
Cheers,

Dear All,

Hello folks.
Thank you for your answer.
Very Strange problem. Just installing the 2 radeons couldn't get me video acceleration.
I had to activate and install HD 3000 onboard graphic card. Then Connect the main screen to several MiniDP outputs and rerun isadora until I get acceleration. Then get back to main DVI output on first card. Then deactivate HD3000 on bios.
Ok then. 50 fps. -
My Version is 1.3.0f24.
I have a show next week. Should I test the f33 version ?
Can I Have both f24 and f33 versions installed ? -
