Hi,
I am trying to implement different upscaling methods in our nDisplay based simulation for the purpose of testing to see what looks best for our use case. We have tried DLSS which works great, but we are using A6000 GPUs so cannot leverage the power of DLSS frame gen.
We are currently testing FSR to see how it compares, but have ran into some issues. Running our project from editor as a standalone desktop window works great on our rendering nodes. Both FSR’s upscaling and frame gen works well with massively improved performance. However, when we boot the project to our nodes via switchboard using our nDisplay config, we are met with a crash on boot every time. Even with FSR and frame gen disabled in the project settings, we are getting the same crash. The log files on our nodes list the error as line 901 of FFXFrameInterpolation.cpp: ConfigDesc.swapChain = Presenter->GetBackend()->GetSwapchain(ViewportRHI->GetNativeSwapChain());
This happens no matter the version of directx we are trying to use. Our nDisplay setup has 4 nodes each running a 4K projector using the VIOSO projection policy (vwf files, not mpcdi).
I am curious to see if anyone else has tried to run FSR in an nDisplay project? I struggled to find mention of any such attempts, but would be curious to know if anyone else has had a similar experience. Due to this lack of documented usage of the two technologies, I assume FSR does not support nDisplay. If any more info on our setup would be helpful in diagnosing this, let me know.
Thanks,
Dylan
