I’ve been having problems rendering in IRAY using my EVGA RTX 2080Ti Black GPU both in Daz Studio and nVidia’s IRAY server. In Daz Studio’s log file I see the following relevant lines:
IRAY:RENDER :: 1.1 IRAY rend info : NVIDIA display driver version: 465.89
IRAY:RENDER :: 1.1 IRAY rend info : Your NVIDIA driver supports CUDA version up to 11.3; iray requires CUDA version 11.0; all is good.
IRAY:RENDER :: 1.1 IRAY rend info : Using iray plugin version 5.1, build 334300.6349 n, 14 Dec 2020, nt-x86-64-vc14.
IRAY:RENDER :: 1.1 IRAY rend info : CUDA device 0 (NVIDIA GeForce RTX 2080 Ti): compute capability 7.5, 11.000 GiB total, 9.961 GiB available, display attached
IRAY:RENDER :: 1.0 IRAY rend info : Using OptiX version 7.1.0
Iray [ERROR] - IRAY:RENDER :: 1.0 IRAY rend error: optixInit() failed: Unsupported ABI version. Please update your NVIDIA driver
And nVidia’s IRAY server produces something similar, specifically the “Unsupported ABI version” message. This is using the latest nVidia drivers: 465.89. I’ve updated my MB BIOS and GPU firmware to no effect.
Other users report no issues between IRAY and the 2080Ti, though so far they report using different manufacturer/models than what I am so I’m suspecting this might be a problem with the EVGA Black, but I don’t know how else to diagnose this issue. An EVGA rep claims this is an issue requiring the software developers to implement support for this specific GPU.
I’m hoping somebody can help in further troubleshooting this issue: Is it really something that the Daz and IRAY server developers need to address or is there something I can do on my end to resolve this?
