Scenery loading pauses, where the display stops for a fraction of a second or longer, are one thing and common, especially in heavy scenery like OrbX SoCal... Microstutters while flying, especially when looking out to the side, ala "Fluidity" or lack there of, are what I thought we were discussing.. No? My concern was (and it wasn't fully clear in this thread) that 4.5's cpu usage also induced pauses as well. If it does not, that is good, I can focus on microstutters solely.

Then look at process lasso. You'll see your core 0 usage at 100%. Then click on the P3D process and change the current CPU affinity and disallow cores 0 and 1. You'll see the core usage on core 0 drop/ Wait about 10 seconds, then set the affinity so that all cores are used. You should then see all cores pick up. Confirmed, thank you. I never had to do this before in V4, before 4.5 - I think somebody would have caught this long ago.

I only do understand a small percentage of the tech speak, however, isn't that equivalent to the age-old trick to open Task Manager, deactivate core 0 (or any other one) of Prepar3d, quit, open it again and reenable core 0. Which Lockheed Martin's Beau Hollis decidely adviced against as it would destroy the intended Prepar3d task handling?

May 16, 20197 yr @pmb I've never seen that article so its very hard for me to agree. What I will confirm is that this method has given me a few frames and smoothness (the latter being subjective of course). I'll try to find some time to execute a flight with the method I posted and without to see how it goes. Thank you for the head's up! "I am the Master of the Fist!" -Akuma

I don't see anything in 4.5 that makes me want to upgrade and if the small increase in FPS is at the cost of core 0 at 100% all the time then....no thanks. Thanks, guys for finding and sharing this info. Well don't have the urge to go for 4.5 HF1 at this point still on 4.4 🙂 André

Kind regards, Michael QFT. 👍 Of course, I've tried this trick, and P3Dv4 always ran badly when I did. A stuttering, long frame mess even when I pulled all sliders to the left. It was clear to me that something very important in the sim got hosed (maybe... task handing) when I "balanced" the core loads using the Task Manager trick. Greg

Greg Based on the tech discussion, it may actually be the Windows Scheduler that gets "hosed" to use your term.. either way, some folks swear by this and believe that any method to get Core0 usage reduced is desirable.. and others that believe that there may be unintended consequences when you go mucking around in the way that LM and Microsoft have designed their respective platforms.. I just aim for "fluid flight" and right now, with an Affinity Mask keeping P3D's first core reserved for P3D only, I get great fluid flight on the "unlimited fps" setting... Bert

This is something that Windows Task Manager cannot do. CorePrio seems to be for AMD processors only. Is that right? Or is there more than one website? https://bitsum.com/portfolio/coreprio/?

I was talking visuals - 4.4 night fliers are missing out on improvements in 4.5.
