Hello all,

I have a query which I think may be easily answered but harder to solve.

During normal flying ... Carenado Phenom 300 ... from default airfield I am getting 60 FPS with my rig (specs below in signature) Frame rate is limited to 60FPS

Monitoring the Task Manager (performance) my CPU load never exceeds (AMD R9 3900X - overclocked to 4.5) 40% and is running consistantly at 4.43 to 4.47.

On approach into YBBN (ORBX Payware - terrible graphics and actually worse than default YBBN using AUv2)  my frame rate drops to between 5 and 13FPS but task manager information above does not vary. Simple solution is I know, to just uninstall YBBN, but I would love to know why this is happening and I am not brave enough to mention it, or complain about it, on the ORBX forum

I believe that the CPU is not overloading so the problem has to be (to my mind) the GPU (Aorus GTX1080ti) 

Can somebody tell how I can monitor the GPU load and if that IS the problem, is it hard or practical to overclock that.

The GPU is performing admirably with XPlane 11 (60-40 FPS depending on complexity of scenery) and never goes below 40FPS particularly with Vulkan (just installed)

Looking forward to some input here with this one

Regards

Tony

PS God and airline willing,  I am off to OZ tomorrow for about six months of self isolation in Western Australia

The CPU load figure reported by most utilities is the average across all of the cores.  The metric to watch is the per-core CPU load, particularly on the first core that P3D runs on (core 0 unless you did something with affinity mask to change that).  It's quite common to have the CPU actually hitting the wall with Core 0 maxxed out at 100% while the other cores are lightly loaded, resulting in a misleading CPU load figure.  The core running the primary thread on a 4.4 GHz Ryzen is definitely going to be up against the wall, especially with a known performance killer like YBBN.

Real-time GPU monitoring is best done with a utility that'll put the parameters on an on-screen display, such as MSI Afterburner or EVGA Precision.

 

Panning to certain objects and seeing a framerate hit has to do with how the object is constructed, how the textures are mapped to it, etc.

If the object has many many vertices, for example, it's going to eat for cpu cycles.  If the object has special features (like the moving or conditional hangar door, or things affected by the special effects sliders) it is going to consume some cpu time.  If it has renderings on the inside, same thing. 

I'm wondering how you are travelling at this time...I mean, is that wise?  I'm not even sure I could do that if I wanted to, right now.  Be safe if you do it.

 

Mace,

Firstly, thank you all for your responses.

I am not panning ... simply sitting in a vcockpit 

Travelling.  I am living in a village in Indonesia.  Medical facilities are primitive to say the least. I do, however have access to quite a few hospitals a short distance away.  I have to say that my chances (at the moment) of catching this beast is fairly small.  However, with an indigenous people totally and fervently committed to ignoring any laws (particularly Traffic) and with a Police force committed to doing very little unless paid by individuals (read corruption) the odds are dwindling rapidly.  My village is in complete lockdown (by decree) and nothing has changed. A little less road traffic but all the shops etc are still open regardless of what is being sold. Add to this equation, the very limited Covid testing, the lack of good quality medicines and the standard of doctors locally and you have a recipe for disaster. They have a population of 270 million people and less than 7000 have been tested at this point in time. 

Going to Australia has a certain amount of risk, but surviving Coronavirus there is at least a probability. Here, I do not believe it is. So I am going to play the role of that famous Russian character, Ima word not allowedinoff. Please forgive that one LOL

W6kd,

Strangely, I am looking at 12 cores in the task manager performance tab and all cores are working well, except core zero, which is close to idle all the time.  The same applies to Xplane 11, but performance is so much better. I actually meant to mention this in my original post and I was surprised to not see it after I pushed the submit button. To my knowledge, I have done nothing to the affinity mask.

That applies even when I am getting the 60FPS just normal flying and the only other relevant add-on is REX Skyforce3D 

Willy,

Thanks or your link, I will check it out when I get back to OZ.

Thanks again to you all for this information

Regards

Tony

Well, forget panning.  What I mean is, there IS scenery outside the window of your vcockpit.  And depending on the objects out there, they can have varying effects on frame rate.  I remember making the KDFW Terminal D roof, and it is not flat, requiring many vertices to get right.  I went thru 2 or 3 roof designs in gmax before I settled on a compromise that gave decent performance while still looking ok.   I'd pan to version 1 of my Terminal D building, and it tanked frame rate.  Later versions, not so much.  Probably at Orbx YBBN you're seeing a combination of complex objects and effects there.  I don't have that scenery but that's my guess, based on other Orbx airport sceneries I do have.
