nx2:vi2: crop presents to their frame size and honour RGB10A2 images

2026-11-01T19:59:07+00:00

Present word 7 holds the size of the frame drawn into the image's top-left corner, and image preference word 6 its format (1 RGBA8, 4 RGB10A2). Fire Emblem: Fortune's Weave draws 1280x720 RGB10A2 frames into 3840x2160 images; showing the whole image as RGBA8 gave a corner of wrongly decoded pixels.

[vulkan] 3rd Vulkan Global Maintenance (#4189)

2026-07-09T02:22:43+00:00

Following the philosophy on the previous Vulkan maintenance PR's, this one is reviewing the video_core to resolve VUID's related to the missing handling/ safechecks (UBO's case on missing StorageBufferAccess 8/16 bits on QCOM drivers, resulting on bad compute pipeline compiled), wiring topology representative to EDS2 configuration (following #4117), refactored the sampled image access via new memeber function for type "typeless" which adds a handling on the integer mistmatch (uint to sint, float to uint) + fixing bugs on current texture sampling (int) including the depth/stencil path resolve, maintenance to previous changes on query cache (resolving bugs from #3853), reduced the amount of binding BindVertexBufferEXT2 when a new tick/ frame is presented (with this being a reason for performance reduction on games where vertex polutes the stage, like BOTW/TOTK where grass is draw with vertex); implemented color border swizzle and color write enable for future improvements on EDS3, added initial implementation on Synchronization2 starting a path to ensure an access to VK 1.3 features safely and other smaller fixes along the road.

[vk, opengl] recognize and use ETC2 (if available) textures natively (#3237)

2026-05-15T20:08:09+00:00

this makes it so VK and OGL backends map the NVIDIA's ETC2 into VK_FORMAT_ETC-whatever and GL_ETC-whatever remaps, instead of using the default fallback for AR8G8B8. in short, just make the ETC2 textures be submitted as ETC2 instead of being submit as A8R8G8B8.
