madVR - high quality video renderer (GPU assisted)

    0.90.16

    0.90.18

    Code
    * added new deringing algorithm
* added dering key shortcut and file name tag ("dering(ing)=on/off/half/full")
* fixed: upscaling refinement wasn't always active when doing supersampling
* fixed: Jinc upscaling was replaced by Lanczos3 when upscaling in only X or Y
* fixed: some graphical corruption when combining NNEDI3 + SSIM2D + Anti-Bloat
* fixed: image was too bright with linear light down- and sigmoidal upscaling
* fixed: sometimes HDR SMPTE 2086 metadata got lost

    0.90.19

    Code
    * fixed: image doubling was sometimes activated although it shouldn't
* deringing strength was slightly increased
* deringing artifacts were slightly reduced
* deringing now adds some grain to deringed image areas

    0.90.21

    Code
    * HDR: pixels between 0-100 nits are now left untouched (if possible)
* HDR: improved desaturation algorithms to reduce hue shift even further
* HDR: added option to choose between clipping and tone mapping
* HDR: added option for hue preservation quality
* HDR: added option to restore detail in compressed regions
* HDR: added option to measure each video frame's peak luminance
* HDR: added option to completely disable HDR processing
* HDR: added workaround for files with invalid metadata
* fixed: supersampling + 2D SSIM sometimes produced "green" video

    0.90.22

    0.90.23

    Code
    * updated AdaptiveSharpen to version 2016-07-10
* custom output levels can now be adjusted in 0.25 steps
* HDR: added option to define how to handle too bright & saturated pixels
* fixed: HDR luminance measurements + chroma SuperRes produced green screen
* fixed: #420: chroma was doubled despite being below scaling factor threshold

    0.90.24

    Code
    * HDR: improved tone mapping algorithm
* HDR: added gamut mapping compression (instead of clipping)
* HDR: slightly improved luminance vs saturation reduction formula
* HDR: added options to use an external HDR tone mapping 3dlut
* HDR: added option to do HDR processing, but still output PQ
* fixed: measuring HDR luminance + NNEDI3 chroma upscaling sometimes crashed
* compiled OpenCL kernels are now stored separately for 32bit and 64bit
* when using the "ShowRenderSteps" tweak, a smaller OSD font is used now

    0.91.0

    Code
    * added new NGU (Next Generation Upscaling) algorithm
* added "soften edges" + "add grain" upscaling refinements (atm only for NGU)
* display properties can now also be profiled

    0.91.1

    Code
    * added NGU "low" quality algorithm
* "soften edges" and "add grain" now allow smaller adjustment steps
* fixed: install batch didn't work
* fixed: on some PCs NGU didn't activate
* fixed: on some PCs keyboard shortcuts didn't work
* fixed: NGU grain was static
* "ShowRenderSteps" hack no longer slows down NGU as much as before
* "ShowRenderSteps" hack only slows down stuff as long as the OSD is visible

    0.91.2

    Code
    * renamed NGU quality levels: Low -> Med, Med -> High, High -> VeryHigh
* added a new even faster NGU "Low" variant
* reworked chroma/image up/downscaling/doubling settings pages
* removed NEDI and super-xbr image doubling algorithms
* small speed improvement for NGU-Med (former NGU-Low)
* small quality improvement for NGU-Med/High (former NGU-Low/Med)
* settings dialog warns when SuperRes and NGU are enabled at the same time
* pixel shader database is compressed now to save space

    0.91.3

    Code
    * fixed: NNEDI3 doubling could crash in certain situations
* fixed: NGU chroma upscaling didn't allow "veryHigh"
* fixed: SuperRes strength controls were disabled for chroma upscaling

    0.91.4

    Code
    * redesigned "image upscaling" settings page once more
* super-xbr image doubling is available again
* fixed: downscaling anti-ringing checkbox was sometimes disabled

    0.91.6

    Code
    * added NGU Anti-Alias algorithm, intended as a potential NNEDI3 replacement
* completely redesigned image upscaling settings page once more
* downscaling after doubling now uses relaxed AR (instead of strict)
* increased AdaptiveSharpen + LumaSharpen upper limits
* fixed: up & downscaling anti-ringing checkbox was sometimes disabled
* fixed: 3D subtitle depth was incorrect for movies with swapped eyes

    0.91.8

    Code
    * NGU Sharp now targets middle ground between gamma and linear light
* added NGU Standard + Soft algorithms, with direct quadrupling support
* added true "very high" quality mode for direct quadrupling
* modified "add grain" to produce similar output when using direct quad
* fixed: Y416 input was handled incorrectly

    0.91.9

    Code
    * added support for sending HDR metadata via Nvidia's private API
* added support for sending HDR metadata via win10 (not tested yet)
* fixed: processing (not converting) HDR was not handling gamut correctly

    0.91.10

    Code
    * improved Windows 10 HDR metadata support
* added new option "hack Direct3D to make 24.000Hz and 60.000Hz work"
* performance improvement with "trust DXVA" + "use D3D11 for presentation"
* fixed: Intel GPU driver flickering bug with "use D3D11 for presentation"
* fixed: madVR(64).ax files were larger than necessary
* Intel: 10bit DXVA surfaces are now converted to 10bit RGB (instead of 8bit)
