BetterDummy being extremely laggy on a 2013 MacBook

[Piipperi]

I know it's probably related to my MacBook just being old and CPU being slow, but applying a 2304x1296 resolution to my monitor (plugged into RX 5700 XT) makes the computer very laggy, scrolling thru pages in Launchpad looks like it's at maybe 30 FPS if not lower, and Minecraft running at 2304x1296 got me an average of 30 with dips to low as 10 FPS. Normally I can run Minecraft at over 100 FPS in 1080p, and even then it's purely CPU bottlenecked. Dragging a Safari window around as well is pretty slow.

MacBook Pro (Retina, 15-inch, Late 2013), 12.1 Monterey

Hi, probably mirroring from a virtual screen is slow in this architecture. The app is mostly tested and optimized for M1 which is basically doing hardware mirroring for virtual displays. The speed difference was obvious compared to a 2018 Intel Mini I was testing as well.

Alright, that was my suspicion too. Thanks for confirming

Is it true that Apple Logic's performance is affected when being scaled displayed?

[waydabber]

Using a larger desktop, and the use of scaling will require some system resources - on older Intel systems or systems with low amount of RAM this might negatively affect the performance of the system in general. Using streaming instead of mirroring also taxes the system more. I don't know about Logic specifically, I don't see a reason why it would be especially affected, but I am unfamiliar with that app.

Thank you for the reply! Which process would take more CPU? Coudl this be seen in the Activity Monitor ?
