- upgrade the project to 4.3 and create another development build
- start both build and notice that the performance of the 4.3 build is lower

    Downloaded 4.3.4f1, totally fixed. Camera.render went from 115ms to 11ms.

    On a project where I was consolidating textures to improve static batching. Editor and web builds consistently improved, PC builds went down the drain.

    We are seeing an fps drop from 70 to 30 on our windows standalone build using unity 4.3 vs 4.1. We do static batching, but now it's pretty much useless. We can't release this version of the game until we have a solution for this!

    This isn't fixed. Performance (FPS) is still significantly lower than it used to be. I'm working on iOS and my game used to run at 60 FPS on an iPhone4. It never goes above 35 after switching to Unity 4.3.1

    Enabling static batching on basic geometry (ground, buildings) causes frame rate to go from 60FPS+ to <20FPS. Disabling it causes it to shoot back up to 60FPS. Doesn't make a difference if static is enabled to meshes or meshes with LODS. View being rendered is about 500K vertices and similar # of Tris.

    This really does need to be addressed. I'm having the same issue.

    Seeing a significant drop in performance ( 60 -> 24 fps ) on Windows build. Fullscreen Editor runs at 60 FPS on the same machine.

    In my case it was a 4.2 project updated to 4.3 it runs fine in the editor but the Windows Standalone has significant performance loss of at least %50 and my 21" 2011 iMac appears to suffer from odd stalls which slowly recover over time.

    [QUOTE=Arowx;1426636]It looks like quite a few people are noticing a performance drop on PC builds in 4.3

    To test this try the following CubeMark builds.

    CubeMark 4.2 - [url][/url]
    CubeMark 4.3 - [url][/url]

    CubeMark thread - [url][/url][/QUOTE]

    Just tried this.

    16k cubes at 60fps on build 4.2
    4k cubes at 60fps on build 4.3

    So Unity 4.3 is a 4x performance drop.
