One more question, does DLSS support ScenceCapture/Composure?
When I turn on TAA on the SceneCaputure, it seems use TSR instead of DLSS.

3

Oh that’s odd, this is exactly the same bug I have…

4

Ok this might need its on entry but the plugin streamlineDeepDVC is compiled for 5.3.0 and I am on 5.3.2. Aside from me recompiling manually for 5.3.2 , is it possible to release the updated plugin ?

5

Update on my last comment. The DLSStest sample was complied for 5.2 and was causing the issue, NOW i also have the same CRASH noticed by the contributors here. Did anyone address the cause or found a solution? Interestingly, I have no crash when launching as standalone game but it crashes when launching through Switchboard. any thoughts?

Hi guys,

I can’t help immediately, but I’ll forward the error above to the Streamline/DLSS experts.

Does anyone happen to have somewhat more verbose logs with all the DLSS/NGX and Streamline log flags enabled?

Thanks!

Oh and @jz.fan it would also help if you gave some detail on what you were trying to run when you encountered the issue.

Thanks

For me the problem lies here
\Streamline\Source\StreamlineCore\Private\StreamlineViewExtension.cpp
image
I have to manually set it to ENGINE_MINOR_VERSION < 5

I get the same error message and tried your fix to change the cpp file, with a text editor, in the plugin directory. But I still get this message. Do I have to reload the plugin or do something else…? I use DLSS 3.7.10 and UE5.4.2 . I get the error when I start my game in VR.

10

You have to re-compile the whole project using Visual Studio.

11

I tried it with a fresh blueprint project, it does not work and I also tried it with a C++ project and recompiled it with VS same error message :(

12

Did anyone solve this issue? I read maybe a solution would be to insert streamline 3.5 instead of 3.7.

13

For the “Assertion failed” , the Minor revision variable will be 3 for 5.3 or 4 for 5.4. By forcing to be under 5, I guess you make the check function works. You checked that there are no subsequent errors in the StreamlineViewExtension routine?
