Bad performance of Paraview while rendering .MED files

Hello,

Greetings. I have been trying to use paraview to visualize Code_Aster result files (in .med or .rmed format) but the performance is not too good. The rotations and manipulation of mesh is slow. The performance is further degraded if one uses transparency (by using right click> Set Block Opacity to like 0.5)

Also, Enabling opacity mapping through Color Map Editor degrades performance.

Consequently investigation of results is not easy.

I attach a sample .med file for looking into this issue here: link

I am using the latest version of Paraview (6.2) on Ubuntu 26.04 with Nvidia Quadro RTX 4000 GPU.

Thanks and Regards
