Question Different meshes triangulation for better performance

Hello guys, i have tryed to seach something about it but i haven't found anything. I think my question is pretty simple. If you look at the image you can find a the same mesh but with with different topology. Thr tri count is kinda the same for both meshes. Which one is better for performance?


Thank you in advice!

 

Performance wise I don't think there will be any noticeable difference under normal circumstances. This is not the kind of thing you usually focus on when optimizing performance, unless we're dealing with extremely small triangles. For a detailed report:

However, thin/sliver triangles are generally problematic for lighting and physics. So personally, I'd always avoid them when possible.
