Change Log

Hey, everyone! Today we’re releasing v1.4.1, featuring the below fixed issues and improvements.

Fixed issues:

• Fixed a crash on launch when there is no “newgame” command, for example, when someone overrides the default.cfg file.
• Fixed crashes or corruptions on AMD GPUs by increasing the size of the AS build scratch buffer and using correct scratch buffer alignment: https://github.com/NVIDIA/Q2RTX/issues/99
• Fixed some potential memory leaks as noted in https://github.com/NVIDIA/Q2RTX/pull/84
• Fixed the bloom output jittering when DRS is used.
• Fixed the game not launching on pre-r460 NVIDIA GPU drivers: https://github.com/NVIDIA/Q2RTX/issues/100
• Fixed the non-TAAU upscaling when DRS is enabled and its maximum scale is set to lower than 100%: https://github.com/NVIDIA/Q2RTX/issues/96
• Fixed the render corruption when running the game on GPUs with 6 GB of memory at 4K resolution: https://github.com/NVIDIA/Q2RTX/issues/98 Fixed the SBT size for hit and miss shaders, preventing potential issues with future drivers that might rely on that information.

Denoiser Improvements:

• Reduced the noise on first person weapons.

Misc Improvements:

• Added a driver version check for AMD GPUs to make sure that at least version 21.1.1 is used.
• Added an option to build `glslangValidator` as a submodule.

Hey, everyone! Today we’re releasing v1.5, featuring the below features, fixed issues, and improvements.

New Features:

• Added support for ray tracing using the `VK_KHR_ray_query` extension API.
  NOTE: This is an optional feature, and the two previously supported methods, `VK_NV_ray_tracing` and `VK_KHR_ray_tracing_pipeline`, are still supported. We recommend using NVIDIA Graphics Driver version 465 or newer, or AMD Radeon Software version 21.3.1 or newer.

Fixed issues:

• Fixed the crash that happened on some systems when the game is minimized: https://github.com/NVIDIA/Q2RTX/issues/103
• Fixed the invalid Vulkan API usage that happened in the bloom pass: https://github.com/NVIDIA/Q2RTX/issues/104
• Fixed the invalid barrier for an inter-queue resource transition: https://github.com/NVIDIA/Q2RTX/issues/105
• Fixed the out-of-bounds addressing of the framebuffer array: https://github.com/NVIDIA/Q2RTX/issues/107

Misc Improvements:

• Reduced the delay after resolution changes by avoiding re-initialization of the RT pipelines.
• Changed the memory type required for the UBO and transparency upload buffers to `(HOST_VISIBLE | HOST_COHERENT)`.
• Improved logging around SLI initialization.

Hey, everyone! Today we’re releasing v1.6.0, featuring the below fixed issues and improvements.

Breaking Changes:

• Re-designed the material definition system for flexibility and modding.
• Removed support for the VK_NV_ray_tracing Vulkan extension, which is superseded by
• VK_KHR_ray_tracing_pipeline and VK_KHR_ray_query that were added earlier.

New Features:

• Added a setting to enable nearest filtering on world textures, pt_nearest.
• Added a setting to enable the use of texture and model overrides in the GL renderer, gl_use_hd_assets (https://github.com/NVIDIA/Q2RTX/issues/151)
• Added support for converting sky surfaces into lights based on their flags, see pt_bsp_sky_lights.
• Added support for IQM models and skeletal animation for the RTX renderer.
• Added support for making any models translucent, and cl_gunalpha specifically.
• Added support for masked materials (https://github.com/NVIDIA/Q2RTX/issues/127)
• Added support for polygonal light extraction from MD2/MD3/IQM models.
• Added support for smooth normals on the world mesh through a BSPX extension.
• Added support for unlit fog volumes. See the comment in fog.c for more information.
• Enabled game builds for ARM64 processors.
• Extended the “shader balls” feature to support arbitrary test models with animation.

Fixed Issues:

• Fixed a crash that happened when loading a map with non-emissive lava material.
• Fixed loading of multi-skin MD3 models.
• Fixed long texture animation sequences.
• Fixed some bugs in the model validation code (https://github.com/NVIDIA/Q2RTX/pull/149)
• Fixed some self-shadowing artifacts by increasing the shadow and bounce ray offsets.
• Fixed some unlit or partially lit triangles by improving the BSP cluster detection logic.
• Fixed the MZ_IONRIPPER sound (https://github.com/NVIDIA/Q2RTX/pull/143)
• Fixed the rcon_password variable flags to prevent the password from being stored (https://github.com/NVIDIA/Q2RTX/issues/176)

Hey, everyone! Today we’re releasing v1.4.0, featuring added support for final Vulkan Ray Tracing API, and enabling dynamic selection between the pre-existing NVIDIA VKRay and the new Khronos extension backends.

New Features:

• Added support for final Vulkan Ray Tracing API. The game can now run on any GPU supporting `VK_KHR_ray_tracing_pipeline` extension
• Added temporal upscaling, or TAAU, for improved image quality at lower resolution scales.

Fixed Issues:

• Fixed a crash that happened when there are no available sound devices.
• Fixed a few issues with the tone mapper and the profiler for AMD GPU compatibility.
• Fixed a server crash: https://github.com/NVIDIA/Q2RTX/issues/86
• Fixed black materials and some light leaks: https://github.com/NVIDIA/Q2RTX/issues/55
• Fixed missing railgun lights in photo mode: https://github.com/NVIDIA/Q2RTX/issues/75
• Fixed missing sun light on geometry with invalid clusters.
• Fixed the CFLAGS for MinSizeRel and RelWithDebInfo builds to generate correct debug symbols.
• Fixed the game stuttering on Linux: https://github.com/NVIDIA/Q2RTX/issues/62
• Fixed the issue with all models being missing or corrupted on some maps during network play.
• Fixed the nearest filter when DRS was enabled and then disabled.
• Fixed building the game with GCC10 on Linux: https://github.com/NVIDIA/Q2RTX/issues/80

Denoiser Improvements:

• Implemented a new gradient estimation algorithm that makes the image more stable in reflections and refractions.
• Implemented sampling across checkerboard fields in the temporal filter to reduce blurring.
• Improved motion vectors for multiple refraction, in particular when thick glass is enabled.
• Improved the temporal filter to avoid smearing on surfaces that appear at small glancing angles, e.g.
