Solved U3 performance issues
-
Just one other note ⌠if I completely disable my Nvidia driver (DevMgmt.msc) and max out the poor integrated graphics on my old i7-4702HQ, I still get ~18fps if I disable all shadows, water mapping, shader effects, and use low-rez clouds.
Not great but itâs well above 1-2 fps ⌠so something seems very horked.
The high commit-charge and huge amount of non-paged-pool RAM use seems highly sus. But I donât know what could cause that ⌠memory leak from a driver, typically, but that would accrue over time not show up right after a reboot⌠I am also out of ideas, at the moment.

stupid q but here goes⌠why in falcon gfx it says display9? and why r u on 1024x768 res for 3D?
How many monitors you have on your system?
What are their native resolutions?but even if u have 3 monitors this doesnât justify such low fps.
On which PCI express slot on the motherboard is your 1080 installed?

Because heâs running in fullscreen and if even if you have set output to your monitor and resultion and close the setup screen and come back it will be set to 1024x768 as that is what BMS forces the monitor resolution to while in 2d. Has been theat way with the output dropdown since it came with 4.35
The Display number doesnât tell anything about the numbers of display. Mine shows also 6-9 even so only 3 Displays attached

@seifer said in U3 performance issues:
In your setup, I see the output is quite different from the Resolution. Can you check if there is another option there
Wondering that a Dev is asking that statement
See my answer above -
@oakdesign this doesnât happen to me.
U say u have 3 monitors but u see 6-9. That is 4 monitors.So something funny goes on here, maybe some virtual displays enabled at some time and are left overs? I always see 3 (8 9 10) and I have 3 monitors.
yeap u r right on the 1024res I forgot now itâs different.

@arty yes forgot my spacedesk virual monitor used for tablet as secondary monitor

General suggestions:
-
Make sure to install latest drivers from Nvidia for your GPU (If possible do a cleanup of old drivers etc)
-
In Nvidia panel where you can choose which GPU to run for which apps, select the Nvidia card for BMS (regardless of plugged in or not)
-
Set to Power management mode to âMaximum performanceâ
-
Run some general graphic apps and check performance of your system, maybe the GPU is toasted or something? Do you get expected FPS in some benchmark apps?
P.S - Reported âVideo memoryâ in Windows seem to be always the amount of VRAM + Half of the RAM. So in your case the 16GB is same as the system RAM amount, but itâs just a coincidence. Video memory is reported correctly. GPUs can use system RAM when necessary and the drive decides how and what to put in system RAM (I assume that by resources definitions it gets an idea). Itâs not that healthy for GPU to read resources from RAM, but sometimes itâs a must. Not fun but also no chance to cause such reduction of FPS (Besides the fact there is 0 chances that 4.35U3 can utilize the 8GB of the 1080)

Just an observation. In reference to the screenshots for the NVIDIA Control Panel. I noticed setting are being done from the âGlobal Settingsâ tab. I believe it would be best to use the NVIDIA âProgram Settingsâ tab so you can specifically target BMS to use your NVIDIA setting automatically on startup.
Select a program to customize: C:\Falcon BMS 4.35\Bin\x64\Falcon BMS.exe

@jumo213 very strangeâŚ
I used to have a 1080 with a i7700k and I had 150 fps in TE and 40 on the ground on first day campaignâŚ
There is an interference somewhereâŚ
will be possible in the future for more fps in campaign? in the first campaign i have 30 fps, in TE i have 80 ,is there a solution or will be? i understand campaign is heavier and intensier and many things going on but i think its too heavy .
-
@vfp that is not really the canmpaign that is heavy, it is the number of objects that are in campaign. Check the benchmark TE and you will see your FPS drop a lot.
Having said that, yes, we are working to increase this. In fact, from U0 to U3 there is a 30-40% improvement already. But for low end systems, that is not enough: for example, a 10 FPS would become 13-14. 20 will become 28-30.
On my PC, I get steady 60 FPS in campaign, but FPS drop a lot if flying over a city with tracers. This is something I still need to take a look.
-
my pc is indeed low end but i am only at 1280X1024
i am happy for now, but i plan to upgrade when bms upgrades itself, and not for bms only, but campaign was always more demanding all those years , i really glad if you can increase perfonmance in this field -
Thank you all for your suggestions so far and apologies for the delay.
Can confirm the GPU is OK as Steel Beasts and DCS (at close to max settings) run with out any issue. Have also tried disconnecting the external display and running the game only on the Laptops built in screen but the issue was still there.
Re installed the game and restarted after instillation and re installation and re installed the video drivers but still the same low fpsâŚ
Totally bumbed as i really enjoy playing this sim : (

Strange the Nvidia control panel on my laptop does not have any of those settings?!
I think this is some sort of clue ⌠fwiw I updated my Nvidia driver to 425.31 (~2019) and although the âmulti-display/mixed-GPUâ option goes away, the ability to select a preferred graphics processor still remains.
Does Windows show you this option to âRun with graphics processorâŚâ when you right-click on Falcon BMS.exe?
No i do not have that option, im pretty sure my cpu does not have an igpu as it does not show up in device manager and i have never been able to use it for anything.

mmh on my settings page it says display 17âŚ
Only have the inbuilt laptop screen and one external monitor.

Wait what ⌠the Intel HD 630 (integrated graphics) is visible in the Task Manager screenshot you posted, earlier.
Does DxDiag.exe show anything interesting? (Paste a screenshot here â of both the âDisplayâ and âRenderâ tabs if it has both.)

was going of a old and, apparently incorrect memory. The HD630 was there in device manager and i tried disabling it but that made no difference.
Also tried changing the priority in task manager to real time but still no luck .

@jumo213 Not sure you can disable the Intel part ⌠or what happens if you try ⌠itâs what owns the actual buffers and circuitry which scanout to the display, and external ports. The Nvidia part renders into buffers owned by the Intel part⌠itâs not a separate âcardâ like in a desktop PC, with its own outputs (obvs).
https://en.wikipedia.org/wiki/Nvidia_Optimus
Letâs take it from the top ⌠correct me if I get anything wrong.
You and I both have laptops with that split Intel/Nvidia display technology. (Although my laptop is ~3 generations older⌠looks like they stopped supporting it with driver updates, around 2019.)
Both GPUs show up in Task Manager, but your NVidia console doesnât show the normal dropdown selection to choose which GPU to prefer ⌠like I showed on post #25 above. (I asked a friend with a newer gaming laptop, the dropdown is still there on her system, w/ 1050 Ti so same nvidia hardware generation. )
You get just 1-2 fps in BMS ⌠but other games, and benchmarks like Heaven etc run ok.
My older laptop gets ~50 fps⌠in BMS⌠even ~18f ps with the NVidia part disabled. So we have that as a baseline target for what to expect (ie. your laptop should be much higher).
So, it doesnât seem like your problem is itâs just running on Intel iGPU. It seems more like itâs falling back to software rasterization (WARP) but then I canât explain why your CPU usage is so lowâŚ
The other red herring is your non-paged pool usage so high. Maybe thatâs ok? I just havenât seen anything like it before. Iâm really at a loss, for where to look next.
If no other ideas⌠if this were my machine, I would wipe the machine and reinstall windows. (Backup everything you care about, first! And maybe update the BIOS if needed.) Given the super-high npp and the weird way NVidia driver doesnât seem to understand itâs on an Optimus system⌠just seems like a borked install of something, to me. I give up!

After further investigations found it was a windows update causing this issue, backed up and reinstalled windows to remove the problem update and falcon works just fine now
Thanks for all your suggestions.
