From 61121d1b22cd4aa6537fcc212d08a2e2314ca39c Mon Sep 17 00:00:00 2001 From: lat9nq Date: Thu, 28 Oct 2021 19:04:06 -0400 Subject: gl_device: Force GLASM on NVIDIA drivers 495-496 GLSL shaders currently do not render correctly on the recent NVIDIA drivers. This adds a check that forces assembly shaders for these drivers since they seem unaffected and adds a warning informing of the decision. Developers can disable the check by enabling graphics debugging. --- src/video_core/renderer_opengl/gl_device.cpp | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'src') diff --git a/src/video_core/renderer_opengl/gl_device.cpp b/src/video_core/renderer_opengl/gl_device.cpp index 1e1d1d020..0764ea6e0 100644 --- a/src/video_core/renderer_opengl/gl_device.cpp +++ b/src/video_core/renderer_opengl/gl_device.cpp @@ -181,6 +181,21 @@ Device::Device() { LOG_ERROR(Render_OpenGL, "Assembly shaders enabled but not supported"); shader_backend = Settings::ShaderBackend::GLSL; } + + if (shader_backend == Settings::ShaderBackend::GLSL && is_nvidia && + !Settings::values.renderer_debug) { + const std::string_view driver_version = version.substr(13); + const int version_major = + std::atoi(driver_version.substr(0, driver_version.find(".")).data()); + + if (version_major >= 495) { + LOG_WARNING(Render_OpenGL, "NVIDIA drivers 495 and later causes significant problems " + "with yuzu.
