Stuttering of new builds

[akimikage]

I rarely use SVN builds. I only downloaded an svn build coz I wanted to see how custom shaders look like and 0.9.1 doesn't support shaders. Those two builds are the only ones I tested. The official 0.9.1 is the only build that doesn't have this kind of issue

Edit : I'm going to test if it's the custom shaders I added. I'll post the results later
It still stutter even with a fresh, untouched download
