DUNE - DAW/Graphics lag using samples in Reaper [SOLVED]

[Teksonik]

Ok, this wave has some lags under Reaper, but indeed, so far I'm finding small lags only under Reaper. We will take a closer look into the performance.

Did you test in other DAWs? The lag only occurs in 1 out of 5 DAWs here, Reaper only.

Here are my results with that wav file Tek posted:

Orion x64 = No lag
Acid Pro 10 = No lag
Ableton Live 11 Lite = No lag
Cakewalk = No lag
OpenMPT = No lag
Reaper = Lags

Great, thanks.

It is probably Reaper's undo/redo feature which constantly saves the plugin state- no other host does this. I believe it can be turned off though

Try enabling minimal Undo, as described here:

Just tested and turning on "Save Minimal Undo States" in Reaper solves the lag issue (it was turned off by default here).

I come to say that VPS Avenger also lags with samples! Now I've seen your reply, I've changed that setting and both synths don't lag now! THANK YOU!

Can't believe this little setting could cause so much problem!

I have this same problem with a different synth and had to come back here to find the answer again!
