No hdr seem to work here, not even the unity procedural one and the baked reflection probes, i tried everything i could find but they simply stay all pinky and crashed, that started when i moved to a slow geforce 9500gt computer but even being an old machine it never had a problem with hdr in past games, i simply expected it to render my archviz a bit slower than the other gtx950 machine i have. I have no problem with the 6 sided cube though, but i prefer using hdr maps. My drivers are up to date. Here’s a screenshot of the problem
Regarding the specs of the 9500GT it supports DX10 and Shader Model 4, so it should be fine.
If your drivers are up to date and the card is otherwise working normal, i fear there is nothing else you can do.
That card is 9 years old…thats like telling a 120 years old person to run a marathon…
