必要条件:
PCIe 3.0 (Ivy Bridge+)
4G Decoding enabled. See wiki page Enabling hidden 4G decoding if you can't find an option for it.
可选条件:
(optional) BIOS support for Large BARs (often limited to 2GB)
以下是效果图,在 2GB BAR size状况下多了12%FPS (A卡要用Nimez drivers魔改驱动,N卡是否可行未知)
Will less than optimal BAR sizes still give a performance increase ?
On my system with an i5 3470 and Sapphire Nitro+ RX 580 8GB with Nimez drivers/registry edit I get an upto 12% FPS increase with 2GB BAR size. It appears AMD requires a minimum of 2GB BAR for the driver to take advantage of it not sure about Nvidia.
