System Information
Operating system: Windows 10 Home 64-bit
Graphics card: NVIDIA GeForce GTX 860M (driver version 451.67)

Blender Version
Broken: 2.90.0 Alpha, branch: master, commit date: 2020-07-20 20:08, hash: 731d9f0bfa
Worked: 2.90.0 Alpha, branch: active-fcurve-keyframe, commit date: 2020-07-16 18:15, hash: ea4c327c9772

Short description of error
Optix denoising feature stopped working on the latest 2.90 build but works in the experimental "f-curve" branch. I don't remember updating or changing any drivers during the last two days when it bugged. I've tried deleting and reinstalling Nvidia drivers a few times as well as resetting and redownloading Blender.
The error occurs right after loading render kernels in the viewport and in render mode.

Exact message as seen in the viewport and debug_output:
OPTIX_ERROR_INVALID_PTX in optixModuleCreateFromPTX(context, &module_options, &pipeline_options, ptx_data.data(), ptx_data.size(), nullptr, 0, &optix_module) (device_optix.cpp:433)

Exact steps for others to reproduce the error
It might be just my machine as this is a fairly new SSD.

Thanks for the report. This seems like a graphic driver issue. Please double-check if the drivers are up to date and the hardware meets Blender's requirements: https://www.blender.org/download/requirements

To upgrade to the latest driver, see here for more information: https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

It most probably is. I suspect that Windows 10 interfered with the drivers installation process by trying to install an ancient version of the graphics drivers at the same time as me.

Thanks for the input! I'll be trying to reinstall the drivers in safe mode. If that fails, I guess I'll just reinstall windows.

I'll be waiting, marking as needing information in the meantime.

Same error for me. On linux Debian, NVIDIA GTX 750.
It worked two weeks ago, but not now. I've the drivers updated to the latest versions :
Nvidia smi :

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 440.100 Driver Version: 440.100 CUDA Version: 10.2 |
|-------------------------------+----------------------+----------------------+

The blender logs are :

OPTIX_ERROR_INVALID_PTX in optixModuleCreateFromPTX(context, &module_options, &pipeline_options, ptx_data.data(), ptx_data.size(), nullptr, 0, &optix_module) (device_optix.cpp:426)

Refer to the Cycles GPU rendering documentation for possible solutions:

Hi.
Just in case, apparently yesterday there has been a commit that disables support for Maxwell first generation because apparently it is not properly supported:

https:*developer.blender.org/rBc64b12c0b80bc5a60ff39c7f984d06020009400c

https://en.wikipedia.org/wiki/Maxwell_(microarchitecture)#First_generation_Maxwell_(GM10x)

Edit:
Just to avoid confusion for future readers, I clarify that Optix support for the first generation Maxwell has been restored, as you can see in the commit below.
