Lagging, crashes, takes a while to playback. None of my other programs (Adobe included) do this.

Premiere works fine, After Effects, Audacity, even Sony Vegas runs smoothly with instant playback even with heavy audio and effects applied. But somehow, despite being an audio-only program, Audition sucks. It's slow, lags for minutes with playback and commands, hogs all the memory, and now every time I make even the slightest edit I get a crash report for this file I'm working on.

I tried disabling effects both for clips and for tracks, it doesn't help and even if it did it's not a solution so much as it is a workaround. Tried disabling "use hardware acceleration for drawing", I've sent detailed crash reports, I've downgraded to last year's version of Audition. I've done everything and I'm starting to lose faith in adobe if the program functions this badly.

What am I missing? I'm ready to pull a Ron Swanson and just throw my computer in a dumpster (actually I won't, everything else works fine).

I use Windows 10. Here are the specs:
Processor: Intel(R) Core(TM) i3-4330 CPU @ 3.50GHz 3.50 GHz
Installed RAM: 8.00 GB
System type: 64-bit operating system, x64-based processor
