FlareSim requires an NVIDIA CUDA GPU no compatible GPU was detected on this system. Flare Sim will produce black output. #6

Description

@JaroslavLajta

Unable to use and run Flaresim.

Nuke 15.0v1
NVIDIA Quadro P4000 - NVIDIA-SMI 560.76, Driver Version: 560.76, CUDA Version: 12.6
FlareSim 1.1.0 and FlareSim 1.0.0

I get a black screen from the Node even when there are sources.
The error is also inconsistent, it rarely shows up, usually it is just a black screen. Changing to a different frame or changing settings makes the error appear but then also disappear after changing some values in the Node.

The CMD from Nuke gives normal text outputs. Here is an example from FlareSim 1.0.0:

FlareSim: --- frame 1 ---
FlareSim: 744 bright source(s) above threshold 2.00
FlareSim: 153 active ghost pair(s)
FlareSim: source count capped to 512 by Max Sources knob
FlareSim: ghost blur radius 7 px, 3 pass(es)
FlareSim: render time 1.48 s
FlareSim: --- frame 1 ---
FlareSim: [PREVIEW MODE] grid=16  max_src=100  ds=8  spec=0
FlareSim: 181 bright source(s) above threshold 2.00
FlareSim: 153 active ghost pair(s)
FlareSim: source count capped to 100 by Max Sources knob
FlareSim: ghost blur radius 7 px, 3 pass(es)
FlareSim: render time 0.50 s

Tested it on a different computer, Nuke 15.0v1, RTX 6000.
Same issue, FlareSim requires an NVIDIA CUDA GPU no compatible GPU was detected on this system. Flare Sim will produce black output.
