No, Resizable BAR isn’t the universal performance booster you think it is
Resizable BAR is a feature that allows CPUs to access the full memory buffer of GPUs, but its effectiveness varies. While it can provide performance boosts in certain scenarios, it is not a universal solution and can even hinder performance in some cases. The actual benefits depend heavily on the specific game engine and workload being used.
- ▪Resizable BAR allows CPUs to access GPU memory without the traditional 256MB chunk limitation.
- ▪Its performance benefits are most noticeable in modern games that require frequent data transfers between the CPU and GPU.
- ▪Not all games are optimized to take advantage of Resizable BAR, which can lead to inefficiencies and performance drops.
