Montage video lag

[Muskel]

Under editing my video with bunch of effects is reallly laggy, but after rendering its all fine right but I wanna see where to add stuff which is extreamly hard when the whole clip is just lagging any fix?

I just copy paste from http://vegaspro.helpmax.net/en/using-vegas-software/adding-closed-captioning/adding-closed-captioning-to-video-files/using-dynamic-ram-video-previews/

1 From the Options menu, choose Preferences and select the Video tab.

2 Enter a value in the Dynamic RAM preview (max) box to set the amount of RAM that you want to dedicate to video previews.

The maximum size of the RAM cache is displayed to the right of the control. You must leave at least 64 megabytes available for (more if you are creating complex projects). If you reserve excessive amounts of RAM for your RAM cache, performance may decrease.

3 Click OK.

1 Select the region that contains the frames you want to cache.

2 From the Tools menu, choose Build Dynamic RAM Preview (or press Shift+B). Each frame in the selection is rendered.

Click anywhere in the timeline to cancel.

3 After rendering is finished, click Play Vegas Pro b play Using Dynamic RAM Video Previews. The cached video will play back at the frame rate specified on the Video tab of the Project Properties dialog.

If your RAM cache is not large enough to contain the entire selection, the selection is automatically adjusted to include only the cached region. You can increase the Dynamic RAM Preview max setting on the Video tab of the Preferences dialog to increase the size of the cache.

Are You building Your preview in Dynamic RAM using Shift-B? You need to tell Vegas to render video to RAM first, before previewing.
