|

=== Known issues ===
|
||||
====================
|
||||
|
||||
iss: OBS captures go blank after doing a video restart with the D3D11 back-end
|
||||
exp: device/swap chain re-creation isn't handled by OBS' capture plug-in
|
||||
fix: use the GL3 back-end
|
||||
act: won't fix
|
||||
|
||||
iss: once the GL2 back-end is used, performance drops when switching back to the GL3 back-end
|
||||
cfg: nVidia GeForce GTX 1070 - Windows 7 SP1 x64 - drivers 430.64 and 445.87
|
||||
fix: don't switch back-ends at runtime or upgrade drivers
|
||||
act: can't fix (root cause unknown)
|
||||
|
||||
iss: with GL3 and r_gpuMipGen 1, performance collapses big time
|
||||
cfg: AMD Radeon HD 6950 - Windows 10 Pro version 10.0.16299 - drivers 15.201.1151.1008
|
||||
exp: confirmed: whenever glTexStorage2D is called (even when using that function is the only change)
|
||||
fix: use D3D11 or upgrade drivers
|
||||
act: won't fix
|
||||
|
||||
iss: with GL3 and r_gpuMipGen 1, the GPU-generated mips are corrupted
|
||||
cfg: AMD Radeon R7 360 - Windows 7 SP1 x64 - drivers 14.502.0.0
|
||||
exp: not confirmed: broken barrier implementation?
|
||||
fix: use D3D11 or upgrade drivers
|
||||
act: can't fix (root cause unknown)
|
||||
|
||||
iss: with GL3, depth faded surfaces break anti-aliasing
|
||||
exp: can't fetch from the right sample index because render buffers
|
||||
are used as FBO attachments instead of textures
|
||||
fix: use D3D11
|
||||
act: will get fixed
|
||||
|
||||
iss: strong gamma correction breaks anti-aliasing
|
||||
exp: MSAA resolve happens before the post-process pass
|
||||
act: will get fixed for D3D11 and GL3
|
||||
|
||||
iss: D3D11 full-screen toggles with the 32-bit client freeze myT's PC :-(
|
||||
cfg: nVidia GeForce GTX 1070 - Windows 7 SP1 x64 - drivers 445.87

fix: use the 64-bit client
