Isaac Sim Version 4.5.0 4.2.0 4.1.0 4.0.0 4.5.0 2023.1.1 2023.1.0-hotfix.1 Other (please specify): Operating System Ubuntu 22.04 Ubuntu 20.04 Windows 11 Windows 10 Other (please specify): GPU Information Model: RTX 5070 TI Driver Version: 570.86.10 Topic Description Detailed Description My operating system is Ubuntu 20.04, IsaacSim version is 4.5, the graphics card is 5070ti, and the driver is 570.86.10. I encounter a problem of blurry screen when opening any scene. How can I solve this issue? Screenshots or Videos

Could you please check if this rendering issue persists in the Isaac Sim 5.0 developer preview? It is available for access via the official Isaac Sim GitHub repository. Testing with this newer version will help us determine if the issue has been addressed in recent updates.

’m also using an RTX 5070 Ti, but Isaac Sim is not working properly. At first, I installed driver version 570.124.04, and after a lot of effort, I managed to get Ubuntu to recognize the GPU (from llvmpipe to NVIDIA Corporation). However, I encountered the GPU Foundation error, so I downgraded the driver to version 570.86.10. With this change, I was finally able to launch Isaac Sim, but I’m still experiencing blur issues within the Isaac Sim application window. Isaac Sim 4.5.0 recommends using NVIDIA driver version 535. Does that mean version 570 is not supported? [image]

You can check the driver compatibility of the 50 series. Only 570 and later are supported. I encountered the same issue and got stuck at the same step as yours. I guess we need to wait for their bug-fixing

After testing, this issue only occurs on Linux (Ubuntu 22.04) with NVIDIA drivers 570.133.07 and 570.124.04, while the same setup on Windows 11 with driver 572.83 works without problems. This bug is blocking our team’s work, as we rely on this new GPU and the Ubuntu version of Isaac Sim for our robotics research. Please prioritize fixing this issue as soon as possible. @VickNV

Same problem here with RTX 5080. Is there any updates or expected time of updates? @VickNV

It is an issue with the 50 series hardware and driver and the RTX Renderer, at this time. We have added a fix for this in kit 106.5.3, which should be in the next release of Isaac Sim. Right now Isaac Sim 4.5 is based on kit 106.5.0. Your alternative NOW, is to switch to Kit 107.0.3 of Composer available on Git / GitHub [image] GitHub - NVIDIA-Omniverse/kit-app-template: Omniverse Kit App Template Omniverse Kit App Template [image]

Here is a guide to a super fast way to get the latest Composer with kit 107.0.3 1. Download "git" from https://git-scm.com/downloads 2. Download "git Large File Storage from https://git-lfs.com/ 3. Start a windows command console by using running "cmd" from the Windows Start menu 4. Navigate to the root of c: or d: drive. Example "cd\" 5. run "git clone https://github.com/NVIDIA-Omniverse/kit-app-template.git" 6. run "cd kit-app-template" 7. run "repo template new" 8. run "repo build" 9. run "repo launch"

The reason for incompatibility between Blackwell GPUs and the Kit version doesn’t make sense: The Windows version also uses Kit v106.5.0 but doesn’t experience the same issue. It’s more likely a problem with the Ubuntu driver. [image]

Yes exactly. The driver is key. When I say GPU, I do not mean the hardware itself, but just the driver that controls it. I am glad you got it to work better on Windows. But you need to update to the latest Kit, Kit 107.0.3 to get the full benefits.
