Hey guys,

I used to work and render my videos in 720p and all was finde. But now that I switched to 1080p the preview laggs, which is really annoying for editing. I am using the "Vegas Movie Studio HD Platinum 10".

PC specs:

Intel i5-660K @3.5GHz

16 GB DDR4

AMD Radeon R9 Nano

(tell me if you need to know more)

Does anyone have an idea or a solution?
