So help me understand this. I paid for the deskscapes. tried it out. it does crank the gpu way too much for me to even use as well. in other words its kinda useless. pretty.. but useless. and now? well we've been on BETA 5 for what appears to be going on a year now. Really??!! no updates, improvements nothing? yeah. really regretting buying this thing. I mean I'd use it but not when it's cranking the processor and my pc at 20% plus all the time. lol are you kidding me? how bout some efficiency improvements at least. I mean wth.
Videos use gpu, thats an unfortunate fact of life. That isn't a fault in the product, it is the same as if you ran a fullscreen video from youtube for example (depending on codec as there is naturally a trade between filesize and cpu and gpu usage). Throw in any windows sat above the animations which will be recomposited by the DWM each frame and it is clear animations use cpu/gpu.
Some dreams will use considerably less such as dynamic dreams or static wallpapers with effects applied.
