Ok so reporting back I've put absolutely everything on lowest settings in P3D and with no addons except ASN and PMDG 737 my FPS in the VC was 45. However in the outside view it was over 200. I honestly think we won't be seeing over 60 fps in the VC of any complex aircraft unless they find a way for the clickspots to not affect the FPS,

Has the mouse cursor fps drop been fixed in P3D?

Appreciate the detailed info.  This is very helpful.

Has the mouse cursor fps drop been fixed in P3D?

 Yes. I have not noticed it at all in P3D 2.5/3.0/3.1.

Has the mouse cursor fps drop been fixed in P3D?

 

No, it's still a thing. It takes a lot of CPU cycles to check the mouse against all the different 3D clickspots. The more clickspots a cockpit has, the more FPS drop there is. Obviously if your system is running capped at 30fps and your settings are able to maintain 30+ even with the cursor in the screen then you won't "see" any drop.

Hi Michael,

 

You're correct, I just tested this and observed the results, you would see better performance that way.

 

By starting the sim without an AffinityMask, and then by switching off LP0, then back on again, helps alleviate the problems associated with starting without an AM. This moves the jobs off LP0, gives job 1 a core to itself, no longer sharing with another job, then widens the affinity back to zero. When affinity is narrowed on the sim, multiple jobs are running on the same LP so as to make more work for that LP. The LPs look busier but achieve no further purpose since the main sim job cannot take notice of them all.

 

Instead start the sim with an AffinityMask that already masks one of the first LPs. Better still, try starting the sim with an AffinityMask that enables just 4 LPs.

 

I hate to say it, but I believe unfortunately this technique only works because the performance is poor before setting out. More cores and HT enabled makes it more apparent. There are better ways to improve performance, keep addons off the main sim thread and give it a core to itself.

 

So is what you are saying is that more CPU usage does not really mean better performance I.E because of CPU thrashing due to breaking the internal mechanism without a AM?  At least that is my thought -  higher usage does not always equal higher performance. I can bring my system to its knees by using high SGSS and the CPU usage will drop because the GPU is saturated...

The saying that comes to mind is:   "too many cooks in the kitchen.."

That's correct in your case, because there would be more than one job per core and that's why the core looks well utilised. When in fact we only need allow the sim to split into four jobs with an appropriate AM since even on 4.5GHz class CPUs, 5 cores given to the sim produces too much work for the main sim job and the sim stability suffers. Put bluntly, the sim will not function as well when affinity is narrowed after the sim is started due to ganging up of jobs onto less cores.
