Sorry, shared VRAM is usually a fixed percentage of total installed RAM and not manually configurable.
Would be nice if a BIOS update was to add this feature, is there any chance Acer would listen and do so?
An Acer app like PredatorSense or NitroSense would be more likely. But don't hold your breath hoping for an AspireSense to appear anytime soon. 🙂
Well, it turns out there IS a way to do this, but there is no effect on performance since the iGPU can allocate as much system RAM as it wants. The default 512MB is just Reserved for video memory, and also allows games that check for the amount of VRAM to run.
