We\u2019ve been transparent that Resizable BAR (Base Address Register) is required to get a good experience with Intel\u00ae Arc\u2122 hardware and it all comes down to how the GPU reads memory. In TAP\u2019s words:<\/p>\n\n\n\n<p><em>Resizable BAR is a pretty weirdly-named PCI Express feature and what it does is it allows transactions that originate on the CPU (like reads and writes) that are targeting GPU memory to be bigger.<\/em><\/p>\n\n\n\n<p>So game data like textures, shaders, and geometry are constantly being written to the GPU\u2019s VRAM from the CPU\u2019s RAM. Without ReBAR enabled those transactions are smaller in size and the memory controller gets bombarded with tons of small data transfers. As TAP explains it:<\/p>\n\n\n\n<p><em>That happens on things like scene changes, or when you load a new level or there\u2019s a new effect happening. That\u2019s why when you look at frametime charts you\u2019ll see \u201cReBAR off\u201d will generally result in spikes that were already there getting bigger.<\/em><\/p>\n\n\n\n<p>The solution?&nbsp;<strong>Turn ReBAR on!<\/strong>&nbsp;It\u2019s a motherboard feature so you\u2019ll have to check your computer\u2019s BIOS settings to enable it;&nbsp;<a href=\"https:\/\/www.intel.com\/content\/www\/us\/en\/support\/articles\/000091128\/graphics.html\">check out this Intel Quick Start Guide for a how-to<\/a>.
