Experimental v5 crashes, ev4 works #29
Comments
A very strange error. Have you tried to uninstall the alvr_driver and re-install? Maybe something is stuck. Maybe @zarik5 has more insight, the changes from ev4 to 5 came from him. |
I have Nvidia GTX 1660 Ti. Driver version is 436.15. |
I just upgraded from Visual Studio 17 to 19 and from CUDA 9.2 to 10.1 |
I can confirm that it crashes for me too. What crashes is SteamVR and then I get an error message which I assume it's from SteamVR too? Or maybe ALVR but the application keeps it open and "working" (not hang). V4 works perfectly fine and it's the one that I am using right now. I have tried several times going back and forth with V5 and there is no way of making it to work. I always uninstall and reinstall drivers. There is something on that build that makes it to not work. I don't even enabled FFR. So, unless there is some charasteristic introduced that requires Win10 (I use Win7 right now) I have no idea what could it be. Either way, if for some reason the addition of FFR would require such feature, it would be better if we could still use the software turning it off otherwise people like me wouldn't be able to use the whole ALVR all together. |
@DavisNT the error you reported refers to CUDA; the relative code is executed if "IsWindows8OrGreater() == FALSE". While writing the FFR code I explicitly commented out every CUDA reference because I couldn't compile otherwise (and it wasn't a problem for me because I'm on Win 10). I only touched VideoEncoderNVENC, which in turn creates NvEncoderCuda or NvEncoderD3D11, so I don't see the reason why just the CUDA code would be broken. |
ev5 was build with 17134. With the upgrade I switched to 18362. It should be set to "use latest version" and I hope that works for everyone. I think the big change was the switch to Cuda 10.1. Upgrading was not that hard and Visual Studio 19 and Cuda are freely available. They can even be installed side by side. Just make sure to set the CUDA_PATH environment variable to the one you want use. |
For the rest of humans like me, does that means that it's fixed? When will we see the next experimental release? I am not avid enough to compile and such :( |
I made a release of experimental v6 and hope that its fixes this error |
I can confirm - v6 works well (at least on my PC where v5 always crashed). |
[pull] master from alvr-org:master
Experimental v5 (ALVR server binaries from GitHub release and ALVRClient built from JackD83/ALVRClient@dbaaf13 or JackD83/ALVRClient@7a20a4e + JackD83/ALVRClient#1) is constantly crashing when starting Steam.
Experimental v3 (ALVR server binaries from GitHub release and ALVRClient built from source with the same modification) is working.
All ALVR settings (
%LOCALAPPDATA%\ALVR
folder) on PC were deleted. FFR was not enabled.Excerpt from the crashlog:
Has anybody else faced similar issue?
