How to check XeLL is loaded and working

[donizettilorenzo]

.....instead of latencyflex?
Maybe you can add a specific choice option in the ini (and then optiscaler)?

[donizettilorenzo]

In the log I got this:

"[22:23:25.294309] [D] NvAPI_Diag_ReportCallStart: not implemented, placeholder given
[22:23:25.294327] [D] NvAPI_Diag_ReportCallReturn: not implemented, placeholder given

[22:23:32.171638] [I] LowLatency algo: LatencyFlex
[22:28:49.468562] [I] LatencyFlex deinitialized"

Of course I've put libxell.dll - having an Arc VGA - in the same folder of the exe

It's selected when it's available. In your case - XeLL doesn't support DX11 so LatencyFlex is selected.

As you can see, the selected algorithm is visible in the log or in the menu of OptiScaler if you are using a version built from source code.

Also please be aware that Intel's support for technologies is a total mess. Make sure your card supports XeLL in the first place: https://www.intel.com/content/www/us/en/developer/topic-technology/gamedev/xess2.html

[donizettilorenzo]

But the game is launched in D3D12 via -dx12 parameter (it's the first Ghostrunner) and yes, there's the support

XeSS-SR, XeSS-FG, XeLL

[FakeMichau]

First make sure that the game is actually running in the DX12, OptiScaler's menu can tell you.
Then if you are sure that it does then please set enable_trace_logs=1 in fakenvapi.ini, launch the game, zip the log and send it here.
Please also include OptiScaler's log as well.

Don't know why, but now it works :|

And now NO.....why?

It's RTSS (!)....when enabled (I use the OSD) XeLL is loaded. LOL

Please disable reflex injection in RTSS.

When LatencyFlex is active, can you select "Force LatencyFlex" in OptiScaler menu, apply and then unselect it again and apply again?

That should attempt to initialize XeLL again so please do that when you are actually loaded into the game.

You can verify if xell is loaded successfully by using the latest Nightly Builds on OptiScaler. If it loads properly you should see the following image:

My PC configuration is: i5-1400KF and ARC A770. Below is a simple (though not rigorous) test I conducted using flm.

Testing methodology:

1. Launch the game (Stellar Blade) and wait 10 seconds for the FPS to stabilize.
2. Start the flm test for 10 seconds.
3. After the test is complete, press Alt+F4 to exit the game (ensuring the game remains in the same scene), then proceed to the next round of testing.

Test results:

• With LowLatency disabled:
  

• Using LatencyFlex:
  

• Using xell:
  

According to the "Intel® Xe Low Latency (XeLL) Developer Guide":

"Any other forms of latency reduction or wait inducing technologies like frame limiters should be disabled when XeLL is in use. If the requirement is not satisfied, then timings gathered by XeLL may become inaccurate and might result in undefined behavior.

Passing frame limit to XeLL allows it to enable certain optimizations which would not be available in the case of a separate frame limiter. If an application implements its own frame limiter, the wait operation should happen before xellSleep gets called. Having both an application frame limiter and XeLL active at the same time is discouraged."

Therefore, any form of frame limiter should be disabled when using xell.
