Thanks a lot for answering!
Okay, so I know now what to watch for, which is really helpful. I’ve checked my VSTs, and only one seemed really demanding (DSK synthdrums), but the cpu overloads also in parts where that particular VST doesn’t play. Another VST I use a lot can get demanding depending on how I use it (Synth1 VST) but I love it way too much to let it go haha!
Anyhow, you just thaught me that I can render tracks individually (I thought I could only do that to the master track) and now I can playback my tracks with no problem! Which pretty much solves my problem. 🙂
I find it strange though that with only the 7 VSTs I’m using on 11 tracks on my current project, it makes my CPU usage overload already. Only 7 vstis can be that demanding? I guess rendering is crucial, and it was what I was missing.
Also, if I use a x64 host and x64 plugins, will it make the program perform considerably better?
