I’m using Optix in Version 6.0
my optix application renders well on Geforce GT and RTX cards.
But on a Quadro RTX 3000 with Driver Version 425.45 i have only a black screen. There are no optix error messages.
what can i do? install other driver version? compile on an other optix version? or what can cause a black screen?
Try installing the newest available driver 441.28 for the RTX 3000 board:
That supports OptiX 6.5.0 as well which would be the recommended version when staying on OptiX 6.
Long term you should consider porting to OptiX 7, but that uses a completely different host API.
