Gamers will need Resizable-BAR or Smart Access Memory support on both their CPU and GPU to take advantage of this feature. Resizable-BAR enables Windows to manage GPU VRAM directly, making it the foundation for GPU Upload Heaps.
The feature is already supported by Nvidia, Intel, and AMD drivers for developers. However, it may take some time for developers to assess whether the performance benefits are significant enough to justify implementation in games.
Since the feature is new, it may not be implemented in games immediately. Developers will need time to evaluate its potential benefits.
