Helios and Non-Helios - FPS Impact
-
Hi All, I have a query, maybe a problem or maybe not. Best to ask I guess
I use Helios with the ICE profile and my hardware setup is a RTX3070, with 3 screens on DP using Nvidia surround, and a single touchscreen monitor connected to the HDMI. So 4 screens in total connected from the graphics card. The Helios runs on the touchscreen… obviously.
When I run BMS with and without Helios, I get quite different FPS reporting in BMS and I am unsure why. This is what I get.
Measure : Helios Not Running : Helios Running with Profile
FPS : 200 : 120
Sim : 250 : 160
Ren : 212 : 140To be honest 120 FPS is over double what I had before (I did an upgrade) so it is good enough, but want to make sure I am not missing a trick somewhere.
Any help and or advice would be welcomed. Thanks

@daz and are you testing on the Benchmark TE?
Is your settings set to max performance on the nVidia control panel? -
@Atlas Hi, if you mean the Power Management Mode setting in Nvidia, it is the same whether Normal or Max Performance. For the TE, it is the standard Navigation Training Mission, I just launch it and let if fly for 1min and watch the FPS.

@daz BMS in fullscreen-exclusive mode, or borderless-window mode?
V-sync? G-sync?
-
@airtex2019 Borderless is set in BMS, Surround in Nvidia says not G-Sync Compatible so I am guessing V-Sync.
Another problem I have to sort out, but as of now it says G-Sync not supported on the surround screens.
-
@daz tbh I have no idea if G-sync is even a thing, on multiple monitors… fused into a single virtual monitor
and I suppose I could have told by your fps numbers you don’t have v-sync enabled.
Anyway, borderless means DWM owns the front buffer(s) … and Windows has various optimizations that it turns on or off based on things like presence of overlay windows, and apps on other monitors that are active.
Those opts have come, gone and changed quite a bit over the Windows 10 era, so I don’t have solid advice off the top of my head.
If you run Nvidia Frameview… with and without Helios running. It might shed some light on what composition or flip-modes are actually in effect.
It’s a pretty deep rabbit hole… but those kinds of differences could easily explain the ~few milliseconds difference in your fps numbers.

@airtex2019 ok thanks, I will have a deeper look based on what you have said, this one is a black hole for me so some good pointers to check into.
Thanks
