The hardware acceleration of B570 GPU is not fully optimized for Abaqus 2024 on Win11.

I've encountered significant performance and rendering issues in Abaqus 2024 on Windows 11, which I have definitively traced to the hardware acceleration feature. With hardware acceleration enabled (the default setting), I experience the following three problems so far:

1. Severe Lag During Rotation: When the model displays a large number of nodes, rotating the model results in severe lag and latency. This level of performance is worse than what I experienced on older integrated graphics solutions.

2. Incorrect Mesh Coloring: When visualizing the mesh of an assembly, rotating or zooming the view causes the mesh of some parts to turn dark blue instead of retaining their default light blue color.

3. Broken Transparency and Shading: When in the semi-transparent display mode, changing the view causes the transparency and associated shading effects to disappear entirely.

All these issues are resolved after disabling hardware acceleration by adding abaqus_no_hardware_acceleration=ON to the custom_v6.env file. However, this workaround leads to a significant decrease in model loading speed, severely impacting the overall workflow efficiency.

Following details further pinpoint the rendering incompatibilities:

• Impact of Display Accuracy: When adjusting the model's "Display Accuracy" setting within the Abaqus software, it is evident that the lighting and shading rendering effects in semi-transparent mode also change significantly. With hardware acceleration enabled, only the lowest display accuracy setting can maintain the real-time display of the semi-transparent effect during view changing, although the mesh coloring still becomes incorrect.

• Critical Shading Method Defect: Changing the shading method from the default "Gouraud" to "Phong" triggers severe rendering artifacts. These include, but are not limited to: a sudden shift in the viewport background color, chaotic and incorrect coloring of the model mesh, and complete corruption of the model's lighting and shading effects.

I have attached a video that demonstrates some display issues. Please let me know if any other information is needed. I am eager to help get this problem fully resolved. If full compatibility is difficult to achieve, I will have to consider replacing this graphics card.

Apologies for the delayed response; I've been quite busy recently.

Regarding the BIOS update:
I downloaded the latest update package (7E13v1A) from the link you provided and performed a manual update via the BIOS flash mode. I have uploaded photos of the operation process as an attachment.

Result: No difference from the previous situation was observed.

Regarding the graphics driver update:
After confirming that the BIOS update had no effect, I proceeded to update the graphics driver (clean installation).

Result: The issue still persists and has not been resolved.

Thank you for your patient guidance. I look forward to your reply. Thank you.
