Vegas Pro Problem

[BrownBear - Minecraft]

Hello Freedom!
I had no idea where to create this thread, but i have big problem with my sony vegas pro 13. So was trying to make a montage video and when i try to play the video i have lag on my preview screen and i cant watch. I was watching youtube tutorials and i still have lag i reinstalled and i have the problem again. On youtube a guy said that if you have a bad computer , i would have lag but my pc is good and this happened like one week ago, before everything was cool. can some one help me?

My pc:
AMD a8-6600k 3,90Ghz
AMD 280x
8gb ram // 64 bit

Try allocating a larger amount of RAM to the program.
Go to Options > Preferences > Video > Dynamic RAM Preview
and set it to half of your total ram capacity. I have mine set to 16192, you will need to set yours to 4096.

Also make sure GPU acceleration is on, which is found underneath Dynamic RAM Preview.
