Solved U3 performance issues
-
Sorry i have taken so long,
So checked the correct GPU was selected, disabled my antivirus, and uninstalled/reinstalled the game but the issue remains.
Unfortunately Ctrl + c, f, did not do anything and i was not able to find a āDisplay FPS infoā like command in the key bind menu.As i wrote above this issue is present as soon as the 3D would starts and on all the different missions and campaigns i have tried so far.

@jumo213 Itās
[alt+C][F]
by default to toggle the builtin FPS counter.Post a screenshot of that here, it might help shed some light on the issue. Also a screenshot of the TaskMgr performance tab might offer a clueā¦
Core i7 7820HK
This is a laptop? Sorry I missed that.
Yeah it sounds like itās only using the Intel integrated graphics, not the Nvidia renderer. Iām not sure how to inspect or force that ā¦ or if U3 could have changed anything in that regard.

Windows 10? Ensure āGame Modeā is on, and open the āGraphics Settingsā page to add
Falcon BMS.exe
to the list of apps that trigger high-performance mode.I think that signals the NVidia GPU to be used. (Not sure. But if you had done that for U2 previously and the exe is now in a different placeā¦ maybe it would cause what youāre seeing?)

@airtex2019 Yeah it a Alienware 15r3, windows 10 build 19043, BIOS and drivers up to date.
Have a screen shot of task manager but idk why the FPS counter just is not showing.
-
will try rolling back to U2 to try and narrow down the issue

@jumo213 FPS counter
Press Alt and C, Release Alt and C then press and release F within a second -
@oakdesign Thanks that worked : )
Strange, falcon is seeing system memory is instead of the GPU memory ā¦

Done but issue remained

@jumo213 Weird, that screenshot of taskmgr is not showing much usage of either Intel HD 630 or the NVidia 1080
As if itās falling back to software rasterization ā¦ but in that case CPU would be closer to 100% not 16%
Hmmā¦

has switching to borderless or windowed any effect?

@jumo213 please disable vsync and see if it helps.

I have an old work laptop with the split intel/nvidia graphics interfaceā¦ 4th gen i7 and GT 750M ā¦ probably one of the first of these things? lolā¦ but I can try to play along
With 4.35.0 Iām getting about 27fps with 100% usage on the NVidia GPU ā¦ ~25% usage on the Intel IGP
Laptop screen rez is 3200 x 1800 ā¦ no external monitor.
Here are some settings to take a look at

The concept of āvideo memoryā is complicated on these split intel/nvidia laptop systems. The Intel part owns the frame buffers; the NVidia part can render into them. Each possess some of their own dedicated VRAMā¦ but also a special bridge to system RAMā¦ size determined by the respective drivers.
Start / Run ādxdiag.exeā and it will show you a little better breakdown. Also look at the GPU 0 and GPU 1 tabs on TaskMgr, to see their usage.

No effect i am afraid.

I didnāt ask to see the āMemoryā tab on TaskMgr but I just happened to notice, your non-paged pool usage is astonishingly highā¦
Itās rare to see more than about 250MB consumed from the non-paged pool ā¦ your system shows almost 1GB.
(The non-paged pool is where the core of the OS kernel and some device drivers, run in a region of memory that can never be swapped out.)
I thought it was maybe something to do with the intel/nvidia graphics memory sharingā¦? but on my Optimus laptop the non-paged pool is still just 220MB.
What else do you have running on this laptop? (What is it like, after a fresh reboot?)

Strange the Nvidia control panel on my laptop does not have any of those settings?

Nothing else running to my knowledge, started the computer, launched falcon and took the screen cap. But here is a screen shot if the memory page after restarting.

@jumo213 Hmmā¦ well my NVidia driver and console UI are pretty old. Circa 2017ā¦ Iāll try updating to see what happens. Not sure any newer driver updates exist for my old laptop GPU tho.
Anyone else here have a more modern, Optimus laptop (viz. Intel/Nvidia hybrid graphics)?
