According to recent tests by Digital Foundry, as well as complaints from early adopters, the problem causes severe stuttering, making gameplay nearly impossible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The issue first came to light in early July when players reported frequent freezes and frame drops on Reddit. Digital Foundry has since confirmed the findings in their own benchmarks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"severe-stuttering-in-popular-games\">Severe Stuttering in Popular Games<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In Hellblade: Senua\u2019s Sacrifice, stutters occurred immediately, with frame rates dropping to 0 fps for several seconds at a time. Similarly, Sackboy: A Big Adventure suffered massive performance hits whenever new visual effects were triggered \u2014 something as simple as popping a bubble caused the game to freeze briefly.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"720\" style=\"aspect-ratio: 1280 \/ 720;\" width=\"1280\" controls src=\"https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/videoframe_3052.png\"><\/video><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The freezes appear to be linked to on-the-fly shader compilation. In Sackboy, the stutters disappeared after an effect had been loaded once, pointing to an issue with the initial shader compilation process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Digital Foundry\u2019s Alex Battaglia noted that Returnal ran smoothly during his initial tests with ray tracing enabled, but he warned that the game has a very short pre-compilation phase, meaning the bug could still appear later in the campaign.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-s-causing-the-problem\">What\u2019s Causing the Problem?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On RDNA 4-based GPUs, shaders seem to take significantly longer to compile during gameplay compared to other architectures. This unusual delay suggests a possible driver-level issue or even a deeper architectural bottleneck within RDNA 4. Competing GPUs from NVIDIA and Intel do not exhibit this problem.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/amd-radeon-9000-series-gpus-1024x576.webp\" alt=\"AMD RDNA 4 GPUs Hit by Shader Compilation Issues in Ray-Traced Games\" class=\"wp-image-3787\" srcset=\"https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/amd-radeon-9000-series-gpus-1024x576.webp 1024w, https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/amd-radeon-9000-series-gpus-300x169.webp 300w, https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/amd-radeon-9000-series-gpus-768x432.webp 768w, https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/amd-radeon-9000-series-gpus-1536x864.webp 1536w, https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/amd-radeon-9000-series-gpus-18x10.webp 18w, https:\/\/geeksace.com\/wp-content\/uploads\/2025\/07\/amd-radeon-9000-series-gpus.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Digital Foundry confirmed that they are sharing their findings with AMD, urging the company to investigate and release a fix as soon as possible.<\/p>","protected":false},"excerpt":{"rendered":"<p>AMD\u2019s latest Radeon RX 9070 and RX 9070 XT graphics cards, powered by the RDNA 4 architecture, are running into major performance issues when ray tracing is enabled in Unreal Engine 4 titles using DirectX 12.
