You might try going to the control panel, selecting "system configuration" and then selecting "diagnostic startup". You then have to restart the computer. This disables many unnecessary processes and on my computer makes resolume run smoother. The only problem is that you can't use the Audio in because that is disabled also.
Another helpful program is "Game booster" which also disables unnecessary processes.

i've been running the res 4 demo for a few days now and am noticing a few random stutters here and there when i play clips... the clips are all .mov, 1024x576, dxv, 25fps ... and i'm only playing one clip at a time, no layering. they range in time length from 30second to 3minutes. unfortunately the material within the footage clips is subtle and slowly evolving with allot of lush detail that helps keep the eyes glued to the screen so when the stuttering happens, it feels really obvious and really bad.
i'm working on a macbook pro. i bought it brand new in march, 2011 with all the highest features added in... i've recently reinstalled osx so there's only ableton on there and the res 4 demo. is there something i could do for my system to make this problem go away? this is a fairly top of the line mbp but with the stutters, it's like having your music glitch out in the middle of a set... totally noticeable and totally NOT pro.
any feedback on how to optimize osx or get rid of the stutters would be awesome!
There are two main problems being lumped together in this thread.
1. Jittering playback in slow moving clips, where the playhead continues to play smoothly (most noticeable on clips with horizontal scrolling content).
This is caused by discrepancies between the clips fps and the refresh rate. If your clips are 25 fps (or 50, or 60, or 29.97) and the refresh rate is something other than 25 (or 50, or 60, or 29.97 or an exact multiple of that), sometimes the screen has to display a particular frame longer than other frames. This causes a tiny perceptual slowdown of the footage. We are experimenting with different techniques to lock this down, and have made some progress in the update mentioned, but it continues to remain noticeable if you are indeed 'glued to the screen'.
2. Jittering playback in all clips, where the playhead also struggles (most likely accompanied by a drop in the fps).
This is caused by the system not being able to keep up with getting all the data. Either the problem is the CPU is overloaded because a non-optimized codec is used, or the read speed of the hard disk is not fast enough to read all the data. We recommend using SSD drives with DXV encoded footage for the best results.
I am having similar issues with playback smoothness. I have random periods of "stuttering" of all (2) clips synchronously. However, this is not accompanied by a drop in FPS. FPS is constantly 59.98. It should be noted that one of these clips is a stock Resolume footage shop clip (RebelOverlay-DigitalWarfare_digi_1.mov); DXV 800x600 30fps. The other clip is DXV 30fps 1024x768. Composition contains 2 layers, 1 column, and only these 2 clips. No scaling for either clip, no scaling for either layer. No audio. Global effects and blend modes disabled. Composition size matched to display resolution, to ensure no output scaling. Mac OS X graphics switching off. No monitor, external 1920x1080, and triplehead2go at various resolutions all exhibit the same problem. Each clip is on a seperate internal SSD. Blackmagic Speed Test read results for these drives: Boot SSD 180 MB/s, Internal storage SSD 259 MB/s. atMonitor reports disk read i/o between 1.3-1.8 MB/s during playback of these 2 clips.

seems the radeon gpu is not activated....
macbook is connected to power supply?
maybe you need Updates or Lion for proper graphic drivers.
Power adapter is always plugged in. I have gfxcardstatus to select/monitor which gpu is in use. I have it set to only use the Radeon. The problem is worse when I switch to the integrated Intel GPU.
Now on Lion 10.7.3 and no change. Mac OS X support is seemingly nonexistent on the AMD website. I have reduced the composition to one layer, playing the stock Resolume clip (RebelOverlay-DigitalWarfare_digi_1.mov), and I'm still experiencing the stuttering. Is anybody getting good results with Windows on this i7 macbook pro with the Radeon 6770m?
I think it's some bug in the resolume engine. I spend days to test one clip on different system (win7 i7 system, macbook pro, win xp) with one clip (30fps, 1024x576) and i have the stuttering on all systems. It's randomly and u see the progress bar also stuttering inside the interface. When i play the clip inside quicktime everything is fine. The clip is dxv encoded, without any audio.
I have 3 engines to test the clips, i7 with ati 6950 win7, i7 2 nvidia gtx 560ti sli win7, macbook pro. None of them is playing really smooth.
