Framerate performance...

[gpvillamil]

I just wanted to highlight that Resolume 3's performance needs to improve a bit before release...

I'm getting about 24fps with 3 640x480 layers, on a very very powerful system (Core 2 Duo 2.8Ghz, 4GB RAM, 7200 RPM drive, FireGL graphics card). Same footage on Resolume 2.41, 3 layers play at 40 fps.

Hardware accelerated programs, such as Max/MSP 5.0 in OpenGL mode, manage to play 3 clips simultaneously at about 60fps.

Since Res 3 does use hardware acceleration, I would imagine there is a huge potential for improvement, and that current performance is due to the beta state, debugging, etc.

I just wanted to make sure this is on the radar screen...

What OS are you using? XP or VIsta? All or tests show that Resolume 3 is much faster than Resolume 2.
There might be some incompatibility with the FireGL graphics card, some users have repotted that it does not work at all on this card.

Yesterday I tested 5 layers with some small effects in 720p and the framerate was constantly at 20.x fps and I was very happy with it.
The footage was picvid mjpeg 720p (do not remember the compression rate but I think this is an important aspect too) and i used a 2,6 core 2 duo, 8600 gt and xp.
I also noticed some weeks ago on a test (obviously without resolume) that the picvideo mjpeg codec was much faster than another mjpeg codec (if i remember right it was the morgan mjped codec). So i guess my point is that a lot of things hardware/softwar can influence the performance ... and because of all that stuff which changed in the new resolume there have to be made some adjustments to get the best performance out of it.

I am using Vista SP1. On that system, Res 3 is 24fps, Res 2.41 is 40 fps. The graphics card is an ATI FireGL 5700, which is the same hardware as the ATI HD3650, just a different driver set. Res 3 does work, and well, albeit much more slowly than I would have expected.

On Windows XP (Athlon dual core 2.2 Ghz, nVidia 6800, 7200 RPM drives), Res 3 is 24-26fps, Res 2.41 is 24fps.

(A Max/MSP Vjing patch that I wrote, using OpenGL, runs at 24fps on the XP system and 60fps on the Vista system, roughly what I would expect. That puts up 3x 640x480 MJPEG clips on a 1920x480 screen.)

i had the same kind of thing. insanely powerful as far as gpu goes (8800gtx 768 meg of ram). 3 640 picvideo clips running at around 35 fps...
i can do a software hack with rivatuner that opens up extra maths capabilities, making windows recognise it as a quadro 4400. ive gotta check some stuff before i try it out tho.
ive also got to try out the omega drivers...

I'm getting consistently good performance (35-40fps) on the following laptop system:

Core 2 Duo 2Ghz
2GB 667 RAM
NVidia Go 7900 GS 256 MB dedicated
XP Pro SP2

3 layers, with 3 composition effects (inc. Film Bleach, Luma Rays, Pixels in Space, Trails)
1024x768 (though the clips are 640x480 scaled by 160%)

This is well above what I was getting in R2.41

ok so after some trial and error, ive managed to stabilise my framerate.
turns out it was my own stupid fault
while i was re-rendering all my videos, i had moved them onto my 7200rpm system drive, so when loading clips, resolume was competing for hd resources with windows, the video clips, and itself
what tipped me off was, i had my music turned down low, and when i loaded in the deadly third clip, that usually dropped the framerate down to 19, my hard drive starts clicking away like an over excited cricket, and stays that way for a good 30 seconds. then all goes quiet, and the framerate steadily rises to just under 30fps.
looks like its an especially good idea with this version to make sure there are no bottle-necks in the system...
