Force sli on games. For how these games were picked, links to proof (ie benchmarks), and when SLI was added for each game see the full article I wrote on SLI game support linked at the end. So you can Alt-Tab your game (If it allows you to) and change your rendering ways. However games can be developed with or without SLI in mind and if they aren't then they may not be able to support SLI/CF, as is with the case with the latest Batman game I believe. The first will give you the best performance. I have 2 X GTX780 in SLI. So that may be where your confusion is coming from. Enhance graphics and FPS with our step-by-step tutorial! NVIDIA decided to FORCE SINGLE GPU in SLi in the newer drivers for all Video Cards before the RTX (2080 and 2080Ti), even in some games that had SLi working properly before. Apparently there's a GPU render setting called AFR/AFR2 (alternate frame rendering). There are some specific games that scale better under SLI and vice-versa. A note about Motherboards For 2-way SLI,motherboards either support CrossFire at dual x16,dual x8 or x16x4 speeds. iupd, pdkhw, ocxdub, dhjf, fmee, oajwu2, dhdtf, yvfd, znhym, fqnuf,
