[Technical question] VRAM increase healthy for the deck? #138

I was wondering if there has been any long term testing so far, if the action of increasing the VRAM to 4GB comes with a shorter lifespan. I think if Valve set it to 1GB, it may have a reason. Can you please enlighten me in this regard, would like to use the tool to the best of my knowledge and belief, if subsequent damage to the hardware can be completely ruled out.

The VRAM increase is perfectly healthy as all it does is set a reservation on existing RAM, which can't wear out. The reason it's not default is because the dynamic allocation should be performing identically, but there's a "bug" where fully saturating your memory will evict the contents of VRAM.

Basically, if the game uses at least 16GB of total RAM+VRAM, then this will benefit you with no downsides. If the game uses less than 4GB of VRAM but can consume up to 15GB of RAM, then you might have slight performance loss by doing this, but no permanent damage can be caused in any case.
