Hi Donalf,
- What programs do you have running aside from the editor? The editor is a performance intensive program so if you have a lot of other programs running it could easily cause lag.
- How large is the project you are working in?
- Are you using a significant amount of particles or materials that need shader compiling?
- Can you tell me what your average FPS is in the editor when you see the stuttering occur? You can do this by opening the console command and typing ‘Stat FPS’, then press enter.
- Can you post a copy of your dxdiag here so I can take a look?
- Does this occur in a clean, blank project with no additional content?
