And that Nvidia chip generally hits 60 fps-plus in the Witcher 3 at 1080p High.<\/p>\n<p>So, you&#8217;d expect a reasonably playable 40-something fps from Panther Lake. Add another 35%, and you&#8217;d have a pretty decent experience, though the boost may be fixing what was a slightly anomalous performance in that title for Panther Lake.<\/p>\n<p>The new driver also promises more performance for Intel&#8217;s now elderly A-Series GPUs, such as the Intel Arc A770, though in this case, it&#8217;s Resident Evil Requiem that receives more frames. In this context, Intel is actually claiming up to 40% average fps uplift at 1080p with Ultra settings and up to 30% boost at 1440p Ultra.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check >\n<div class='image-full-width-wrapper'>\n<div class='image-widthsetter' style=\"max-width:4032px;\">\n<p class=\"vanilla-image-block\" style=\"padding-top:56.25%;\"><img loading=\"lazy\" decoding=\"async\" id=\"vrdtvrqT5RGTnhuFQQe2Tk\" name=\"CoreUltraSeries3\" alt=\"An Intel Core Ultra Series 3 chip held between two fingers\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2026\/02\/new-intel-graphics-driver-claims-a-remarkable-35-performance-boost-for-panther-lakes-nifty-little-igpu-in-witcher-3-at-1080p.jpg\" mos=\"\" align=\"middle\" fullscreen=\"\" width=\"4032\" height=\"2268\" attribution=\"\" endorsement=\"\" class=\"inline\"><\/p>\n<\/div>\n<\/div><figcaption itemprop=\"caption description\" class=\" inline-layout\"><span class=\"caption-text\">Intel&#8217;s Panther Lake has the most impressive true iGPU currently available. <\/span><span class=\"credit\" itemprop=\"copyrightHolder\">(Image credit: Future)<\/span><\/figcaption><\/figure>\n<p>Anywho, exactly where Intel is extracting the performance from the Arc B390 iGPU in particular is an open question.
