4.36 Incredible Performance Boost

Please, keep the reports coming. If we have FPS problems, we want to find out where they are coming from.
Just keep in mind that at this first moment, we are focusing on bugs. Priorities…

I had a lot of problems with frame rates in BMS 4.36. But after tweaking my rig noticed that in Win10 > Settings > System > Display > Graphics setting.
System boosted GPU timing -on, Adaptive refresh rate -on, helped. -
@Tunza affectionately known as HAGS (hardware-assisted GPU scheduling)
basically it transfers some load from CPU to the GPU … for recent-gen NVidia parts (Maxwell and later, I think)
Every system is different but I’d say, if you have 6 or fewer cores and are not totally GPU-constrained, turn it on.
(In Win10 it is still off by default … not sure about Win11. So if it gives you any problems, remember to turn it back off.)

Re: adaptive sync… I paid extra $ for a monitor with G-Sync, and tried really hard to like it, but for flight-sims, I have it disabled.
For flight sims, where the world is constantly moving smoothly by, outside my canopy window, I find having frames delivered slightly out-of-phase is more jarring and annoying than an entire skipped frame.
I just enable triple-buffering and an fps-cap, and be done with it.

@Foxtrot701 Turn off antialiasing and all in game itself and create profile in nvidia control panel for bms.exe - NOT the launcher.exe…
In profile setup just what you want , AA8 AF16 etc … all bells and whistles , see the change., … you must select override app settings for AA/AF.
That works with anything, not just BMS. … but biggest performance boost was in one other sim cough … not dcs… cough
I have amd rx580 and is capped at @60 even with tgp/mav , in 4.36. , that is in fullhd, 1920x1080…
I’ve tried 2k (as i run dcs) , but BMS doesn’t love something, no full screen , just 2k window centered even if set to exclusive fullscreen … weird, bah, but ok. fullhd is enough.
Cheers
OMG! Thank you haha! I’ve been applying settings to the launcher and thinking it was all hopeless lol

I recently got 17 fps on a CAS mission… I never expected this even in DCS. Any heavy (meaning any campaign) scenario is copmletely unplayable for me.:worried
Did the FPS decrease before the battle of ground vehicles, or after the battle, at the moment when a lot of craters appear in the frame?
For me, something similar happened when many craters appeared during and after the battle of several battalions. When looking at this point.

@SpbGoro with U2? (the post you’re replying to was from 4 months ago)
U2 has some hugely significant perf fixes, for large number of nearby ground objects.
-
@airtex2019 Ok thanks for the clarification. My naming was improvised, since I have a Finnish version of the OS and couldn’t find correct English term
Anyways for me it seems to work well (Core i7 / GeForce RTX 3080). -
@airtex2019 Yes you are right, U2 is really smoother than U1 around airbases and objectives. There is less trees around but it’s better for now. Perhaps a better ratio to find for BMS team between more objects and smoothness.
But anyway, what a gap for the last versions of BMS since the 4.35 in the performance area. There was a time where the first day of campaign or flying over the flot were a FPS slowdown or stutter fest… no more or so less… very good job !

With 4.36.2, here are some benchmark results on my rig.
-
Windows 11
-
AMD Ryzen 3950X
-
64 GB RAM
-
RTX 3080 Ti
-
Borderless @ 3840x2160: 50-60 fps on ramp
-
Borderless @ 1920x1080: 50-60 fps on ramp
In a more normal mission, like Instant Action, I typically see >120fps.
What surprised me was that I observed very little difference between 1080p and 4K. I couldn’t tell the benchmark numbers apart in a blind test, even though I would have expected a significant performance bump when lowering the resolution from 4K to 1080p.

@Elegantly that simply means we are CPU bound.
-
@airtex2019 Disabled G-Sync on mine. Was the cause of some extreme flashing/strobing effects on my monitor using BMS. Was like it was messing with the brightness controls. Wasn’t recorded in video capture.

@Seifer
Hmm, while R9 3950X is not the mightiest kid around anymore, FPS for such rig are still a bit low. May I ask what is current bottleneck? IIRC BMS performance doesn’t scale that well with more CPU cores, any ideas to change the situation? -
AFAIK single core CPU performance is still the most “limiting” factor for Falcon BMS on top-notch, modern hardware.
All the best,
Uwe

@hoover
Yep, however BMS is already multithreaded it just doesn’t scale that well with more cores/threads.
I’m curious what is main limiting factor here for performance -
@Xeno biggest bottleneck is LOD tree traversal, which is serialized and not cached.
-
@Seifer
I wonder how other sim/games deal with the problem, BMS scene isn’t that much complex compared to modern titles. I hope you guys find clever way to deal with this issue. -
Do not misinterpret @Seifer as saying we should turn off trees.
-
@Xeno we already have a new database format that is more efficient than current one. The idea is to try to bring it to the next big version, but we will see.

** looks around in guilt as he turns trees back on…
