FSHud Performance Latest Beta Build

Recommended Posts

Posted (edited)

Does anyone else see severely degraded performance with the latest build? I'm not sure if it's the extra calculations for separation but since that came out, I'm getting horrid stutters starting on descent when FSHud manages all other aircraft approaching my destination. As if FSHud wasn't hard enough already on performance (15 FPS loss with 20 parked and 20 active aircraft), it now hammers my CPU so much from descent onward I'm getting stutters that make flying in VR nearly impossible because the picture is sort of wobbling around like with motion reprojection when you don't get enough FPS. The in-game FPS counter is frightening too look at. FPS seem (as bad) as before this update, but the stutters are awful. As soon as I closed FSHud today my FPS jumped up by about 20 and stutters were gone completely.

That's on a 7950X3D. I guess it's not an issue for someone running frame generation at 80 FPS, but I don't know what CPU you would need for this not to wreck VR performance. The performance difference with and without FSHud running at low traffic volumes is huge.

Edit: Yes, I'm going to report this.

I, too, had CPU usage related problems with FSHud. In my case CPU temperatures became very high, I did contact the developer but this contact did not result in a solution for my problem. I was informed that my problem could be hardware related. My task-manager did not point into that direction.  And so it is goodbye FSHud for me.

I hope you will get a better result out of your contact with FSHud.


Kind regards,
Hans van WIjhe

There is Performance Balancer feature which came exactly to avoid those issues.
There is detailed video on how to properly configure and use it:


Besides that, we continue to release updates almost every week which also affects on Performance.

Thank you

I'm aware of this feature. It works great, but I'm already running low traffic volumes for the sake for performance, so when this feature further reduces the traffic volume there will barely be traffic, which kind of defeats the purpose of FSHud imho.

As for the stutters, something isn't right. This started happening after the separation update. Low traffic (20 parked, 20 active planes) suddenly results in stutters that make flying (at least in VR) virtually impossible on arrival, and unfortunately makes FSHud unusable in this case.

I'm not a software developer, but I don't believe such low traffic volumes should cause such a performance impact, especially since there were no stutters before. I don't think the performance balance feature is, nor should it be a solution for the stutters. As I said before, while FPS do take a huge hit with FSHud running, they are pretty much equal to before the separation update. It's the stutters that are the problem.

Regarding stutters - as you can see in the video, there is lots of AI Traffic and no stutters.
I think it is something that is not related to FSHud CPU calculations for AI Traffic (which is completely stopped when FPS reaches below specified).
Can you please contact us via application tickets for further investigation of stutters cause?

Thank you

Don't think I've tried the Performance Balancer, it's been a while since I last used FSHud. Reading this thread I was thinking if it would help change some core affinities using Process Lasso. 

Anyway, I'm about to load into iniBuilds Heathrow in the A300-600R to do some performance tests. 

But unfortunately I've forgotten how to inject traffic with FSHud. Does it use it's own injector? Should I use the FSLTL injector? What's the difference between BGL, AIG and External? 

If there's a manual I'll be able to find the answers to these questions. EDIT: It's easily accessible from the app. 

Another thing - I'm guessing the Performance Balancer uses the "native" FPS (not frame generation FPS).

I made a video showing that it’s possible to get great performance with FSHud - with the right settings. The performance balancer works great.

Mate, but You have old version. Without separation and FPS balance.

Hey,

how can i get the beta version?

may be someone can help, i have a lot of twice aircrafts on many airports. I use external (FSLTL) and AIG in the FSHud settings.

That’s so strange, I thought I made sure it updated before making the video. It even says “your version is up to date”. Any suggestions what more I can do to get the new version?

It has to be though. The sim is showing the main thread getting hammered with large fluctuations in frame times and as soon as I close FSHud it goes back to normal. I'm not using the performance balance feature.

I will file a ticket as soon as I have the time, thanks.

The performance balancer exactly intended to avoid this (as shown in the video).
The traffic removal happens according second setting (in worst case) - but before, it stops AI Traffic calculations (freeze below FPS) which is using CPU.

I run 50 / 50 and maintain a pretty much locked 40fps with FG in every possible scenario on a 5800x3d. I have no issues with performance.

I see. It uses FPS as a base though, regardless of stutters, doesn't it? FPS are taking a hit whenever FSHud is running, but they are still always within my accepted margin with the traffic settings I use. So I don't have a reason so far to use the balancer.

The stutters are what's causing VR flight to become awful, and as far as I can see frame times aren't taken into account with the balancer. Stutters weren't an issue before the separation update. I also don't believe there should be such performance degredation with a 7950X3D. Something isn't right here.

Not everyone has a 40-series card though and frame generation doesn't work in VR anyway. I'm sure that with FG performance is fine, but these are different use cases. With 50/50 I typically see FPS dropping from 42 to around 29, which makes a huge difference in VR. I think that's quite a performance hit on a 7950X3D and shows FSHud is definitely hard on performance. These numbers are from a dedicated test scenario btw with no programs running that would hit the CPU, other than the sim itself and the PMDG 737.
