Bug Report RAM usage problem when streaming.

So I recently took on using OBS instead of Xsplit both because of the praise I've heard and because it seems to work like a charm on my not-that-high end PC, managing to squeeze out awesome quality with barely any effect on FPS when gaming. However, there's a problem I have when streaming. The OBS.exe starts suddenly using a lot of ram, going from 250-300mb to up to 1.30Gb every five seconds or so. The ram just builds up and resets down to 300Mb before beginning the cycle anew. There is no delay between these cycles.

This is troublesome because I'm limited to only having 4Gb of RAM and when gaming, a streaming software that uses more than a quarter of what is available (not to mention windows and other programs already using something like 2Gb) it becomes troublesome to maintain fluid gaming.

I tried searching around for several issues but found no topics about this. Any help would be appreciated. Thanks in advance!

I appreciate it. Does this only happen when the app is minimized, or does it always happen? I think this may be something to do with directx, but I don't quite know for sure. Windows vista as well? hmm.

I knew it! ...I also have no idea why. Although then again I suppose I can theorize. Let's see.. When minimized, D3D10's Present is not getting called. Maybe then it decides to start buffering data/commands/etc because it thinks the scene is not complete. Another annoying thing is that this does not seem to happen on my computer. Why though, I have no idea. Complete theory, but it's the best I've got.

Perhaps I can call the Flush command.. would have to use you as a tester. You should come around chat some time for some testing, if I'm awake in there.

I have the same effect on my Vista and it makes the RAM jump up to 2GB. I've found out that when disabling the preview in OBS, the bug is always happening whether it's minimized or not. I think that having the Settings window open prevents it from ever becoming minimized (even if playing a fullscreen game) and seems to be a workaround.

It must be something about something being generated, but the flushing code at the end of the preview code not getting ran.

This is kind of an ancient thread and this problem was actually solved a long time ago, and I haven't heard of the problem since. Honestly, I would highly recommend getting windows 7. Vista is not bad, but microsoft really threw it under the bus (then again they do that with all older versions of their software)
