Support for FSR 4 on RDNA 3 comes by way of the latest version of Proton Experimental, so it&#8217;s by no means a stable implementation just yet, but the engineer specifically calls out SteamOS and the <a href=\"https:\/\/www.techpowerup.com\/350224\/pre-rampocalypse-steam-machine-pricing-was-30-cheaper\" target=\"_blank\" rel=\"nofollow noopener\">Steam Machine<\/a> as the target system for the new upscaler support, suggesting that Valve will invest development resources into getting the support into a more complete state ahead of the full roll-out of the Steam Machine. <\/p>\n<p>Curiously, the post also specifically calls out devices with RDNA 3 discrete GPUs and the Steam Machine, suggesting that support for Radeon iGPUs, like the 780M and 890M that largely dominate the gaming handheld space has not yet been implemented. It&#8217;s possible that Valve developers, who <a href=\"https:\/\/www.techpowerup.com\/348178\/valve-engineer-improves-linux-memory-management-for-gpus-with-8-gb-vram-or-less\" target=\"_blank\" rel=\"nofollow noopener\">often contribute to Linux graphics drivers and gaming optimizations<\/a>, may implement support for the gaming handhelds. There are also reports that manually adding support for FSR 4 on RDNA 3-based iGPU systems\u2014via tools like OptiScaler, for example\u2014results in a working implementation of the upscaler.<\/p>\n<p><a href=\"https:\/\/www.techpowerup.com\/img\/EMxY3ZZB1Y39QPRX.jpg\" target=\"_blank\" data-width=\"1169\" data-height=\"960\" data-fancybox=\"g350267\" rel=\"nofollow noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/06\/EMxY3ZZB1Y39QPRX_thm.jpg\" width=\"158\" height=\"130\" alt=\"\"\/><\/a> <a href=\"https:\/\/www.techpowerup.com\/img\/Vy4lCpFeqmZVla7P.jpg\" target=\"_blank\" data-width=\"1004\" data-height=\"296\" data-fancybox=\"g350267\" rel=\"nofollow noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/06\/Vy4lCpFeqmZVla7P_thm.jpg\" width=\"441\" height=\"130\" alt=\"\"\/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Following the recent release of FSR 4 support on RDNA 3 GPUs, Valve engineer, Pierre-Loup Griffais, has announced&hellip;\n","protected":false},"author":2,"featured_media":509587,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[85,46,125],"class_list":["post-509586","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-il","tag-israel","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/509586","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=509586"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/509586\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/509587"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=509586"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=509586"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=509586"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
