Like the title says, why is my Nvidia GPU showing only 1024MB memory in CPU-Z while it's a GeForce 820M with 2GB dedicated memory? The Intel HD 5500 Graphics Adapter shows 2048MB of memory. Also by the performance of some games, I do feel like the GPU is not using full memory or potential and is not performing as much as it should due to something, is the GPU locked or anything? I have it updated to the latest driver.
