- Added a mechanism to compact/free the larger allocations of unused windows (buffers are compacted when
|
||||
a window is unused for 60 seconds, as per io.ConfigWindowsMemoryCompactTimer = 60.0f). Note that memory
|
||||
usage has never been reported as a problem, so this is merely a touch of overzealous luxury. (#2636)

|
||||
- Backends: DX11: Fixed GSGetShader() call not passing an initialized instance count,
|
||||
would generally make the debug layer complain (Added in 1.72).
|
||||
- Backends: Vulkan: Added support for specifying multisample count.
