In reply to Will. did you mean to VR work as 4monitors setup? something like 2x with 720p(stretched) whole scene and 480p only on focus point, overlay (driven by eye tracker). while vr has 2160p native resolution.

In reply to Tom Beckett.

I am exited because you proof is possible to choose GPU used (under zink).
So now why not add option in multi-monitor setup to run another monitor as ExternalVisuals internally and render that monitor on different GPU (with seperate gpu settings, only those without increase of scenery loading time)
maybe even in VR?? each eye its different monitor (camera seperated by eyes distance).
with 16core+ processors and 32GB+++ RAM running multiple copies should not be any problem.
ExternalVisuals monitor would have different FPS without synchronization with another monitors. and every monitor will must be connected to own GPU because sending display through another gpu has big penalty.

In reply to Giancarlo. The fix for orthos was an independent fix unrelated to multi-core

In reply to Dellanie Byron. I See. Has anything else in addition to multi core been introduced to help with the issue? I ask because in terms of performance with 12.4. I am back to where I was with 12.1. (which is still much better than 12.3.)

In reply to Giancarlo. 12.4 is already the fix for ortho.

In reply to Will. We cannot discuss any future plans beyond what is already announced at this time. Please refer to roadmaps for any upcoming changes.

Thank you for this first step into multi core. For the first time since XP 10 CPU and GPU have near to equal FPS on my Mac. And I see a very significant performance increase in areas with heavy scenery (from 12 FPS to 28 FPS). Cool.

However this just makes up for the massive FPS loss I experience since updating to 12.2 (or 12.3?) when using ortho scenery and high resolution mesh. I did read that the devs are aware of the bug. Is there a timeline for when it will be fixed or is 12.4 already meant to be the fix?

I am on a Mac Studio, M2 max, 64 GB

Great post and update. Any plans to address VR performance such as dynamic foveated rendering / quadviews?

Absolutely brillant work. I use scenery addons that add a lot of work to the CPU, like x-world and autoortho. In 12.3 and earlier I experienced stutters when loading new scenery tiles, which took quite a while. That led to ATIS becoming available quite late in the arrival phase often and also forced disconnects from vatsim.

This seems to be completely gone now (had only two flights to test).

Thank you so much. Have a great Christmas everyone.
