I have upgraded to v4 and my performance on my Mac M1 Mini 16GB RAM has been reduced significantly, compared to before.
I also am running Sonoma 14.1.
Is anyone else encountering this issue? What percentage of RAM usage should I put for this version?

AppleSilicon performance has in fact been considerably reduced - but this already before with the 3.5.x versions.
[If you are posting a new bug, please include the following]
The bug / behavior you have encountered
Iris V1 and V2 are extremely slow on Applesilicon with the 2x model. Iris V1 was blazingly fast with the 3.4.0.0.a (where the release notes also stated a speed gain) but that was lost with encoding speed down back already in the 3.4.0 Beta.
When Iris V2 was introduced it had good speed up to the 3.5.0.1.b -but with the following releases speed drastically reduced (about 60% of the former fps…
Only little difference between the last 3.5.x version and 4.x here.
Was you running Sonoma release on prior versions ?

The speed drop is not due to Sonoma itself.
Iris ran the same speed on Sonoma as on the previous OS Version - there were visible glitches, yes, but even those you could circumvent via running TVAI „under Rosetta“ and this without really a speed loss.
Then they updated and the speed was halved.
Similar with Iris V2 which primarily was as fast as Iris V1 before the speed-hampering fix on Sonoma but then also got very slow after another fix for visible glitches pn certain configurations.
So is this software not optimized to run on Sonoma?
Can I achieve the original (faster) speeds by running this software on a previous Mac OS?
Thanks,

No. As said this is NOT due to Sonoma but due to fixes for glitches with certain configurations.
Sonoma + Iris model before the fix = high speed
Sonoma + updated Iris model after the fix = inferior speed
Unfortunately that way those that weren’t affected by the bug were „punished“, too.
