I’ve seen similar comments over the past month. Try the usual checklist:
- Update graphics drivers
- Clean up any programs running in background
- Check your FPS to see if any tabs are running way too high (Ctrl-F or Ctl-Alt-Shft-M)
- Turn on V-sync
- Try it in DX 11
- Adjust post-processing, ambient occlusion, shadows etc. Especially settings affected by recent patches.
- Check to see if it’s only tabs with ships docked in stations, or happens anywhere.
And keep CCP loudly informed if you find that continual graphic fiddling which degrades performance more than it enhances visuals interferes with your EVEing.
