Since this was for an earlier version, is this still valid information?
Some of it. I personally use the following:
VideoMemoryDynamicDetect false // use auto detection of available amount of video memory (VRAM) in runtime
VideoMemorySize 4095 // video memory size to use if VideoMemoryDynamicDetect = false
VideoMemoryMaxPercent 95 // max video memory consumption (percents)
But what works best for you will depend on your own experiences and system specs. Also, it's not as useful as it was before, since SE is better with memory detection and management than it used to be.
