Warning Vulkan Isaac sim 2021.1.1 Ubuntu 2020.04

I am new to Isaac sim but when running Isaac launches with some warnings on ubuntu 2020.04. When importing some of the examples the textures of the assets look bad. After some readings I think it is related to vulkan api so these are the warnings I have:

2021-11-21 08:39:20 [10,209ms] [Warning] [carb.graphics-vulkan.plugin] Physical device with name: llvmpipe (LLVM 12.0.0, 256 bits) does not support 'Vulkan 1.1', it has api version: 1.0.

When loading the output from the terminal:

My system specifications are:
Ubuntu 2020.04 LTS
Isaac Sim 2021.1.1
Nvidia-driver 495.29
GPU: RTX 3080

The issue could be caused by the 495 drivers. Please try installing the 470 drivers.

Thank you for your reply! Unfortunately I tried changing to 470 drivers but the problem still exist. Here it is my full terminal logs:

And Here it is a picture of how it looks for example importing the UR10 robot.

One update here. I installed the recently released new version of isaac sim 2021.2 and the appearance is better. However the warning still appears in the logs. I also tried running the examples in isaac gym but the rendering its ok. The visual now look like this:

I don’t know if I can work with this, or if there is a solution out there. Thanks in advance.

This looks visually correct now
