V2.1

Changes

• Fixed a number of small bugs including overshoot, library location and more
• Reverted graph view template to a much faster version
• Added VSync option
• Added check for Excel being installed as it's COM component is used to write to the results template file. If not installed writing to XLSX heatmaps and graph view will be disabled.

V2.0

Changes

• Dedicated input lag testing mode!
• Addition of input lag to response time measurements
• New test style, desktop program led to prevent runaway.
• Tweaks to the processing code, now auto-generates heatmaps
• Can auto-generate graph view raw files (unstable)
• New case revisions and slight PCB tweaks
• UI redesign (still looks terrible, sorry)
• New options including "Recommended Settings" and "Advanced Settings".

Known Issues

• Overshoot above maximum not reported correctly (hardware issue)
• Error handling still not perfect, tests may fail/fail to process, no on-device checks and automatic capture time extension

On the TODO List

• Estimation for clipped (over max brightness) overshoot
• Live view / oscilloscope view
• Input lag testing using live games (variable trigger point)
• The inevitable onslaught of bugs you lot will find...

V1.8

Changes

• Fixed issue with program running the gamma test then cancelling
• Made changes to prevent updater running into itself during an update.

Major functionality change incoming

I'm working on changing how the program/device run the test sequence for better control, which should help catch 'runaway' events which require the device to be unplugged to resolve.

V1.7

Changes

• Reduced test pattern to 6x6 (0, 51, 102, 153, 204, 255)
• New dedicated gamma test for better accuracy
• New gamma processing with cubic interpolation
• New system up-time check
• Fixed numerous bugs with processing, updating and more.
• Improved case design

V1.6

Changes

• Improved start/end averaging to get better start/finish points for GtG measurements, and more accurate overshoot figures
• Added mid-run pause if the game window isn't selected, meaning you can ALT+TAB and it should pause the test then when you select the UE4 window again it will continue
• Added Graph View Template to let you manually verify results and will auto-calculate the complete and 10% response times once you pick the exact start and finish points. Will also calculate overshoot.

Known Issues

• Overshoot / Undershoot will calculate from any point on the array, not only within the transition window.

V1.5

Changes

• Added Graph View Template (over/undershoot calculation isn't perfect!)
• Improved clipped curve measurements
• Started improvements for overshoot

Known Issues

• Overshoot calculations aren't completely remedied.
• Firmware update addition needs to be removed on next update.

V1.4

Changes

• Fixed debug mode
• Tweaked firmware update message to include current & new version

V1.3

Changes

• Timing fixes in firmware
• Minor bug fixes and tweaks

V1.2

Changes

• Fixed hardware timing issue
• Added minimise to tray or taskbar option
• Added launch check for other copies of the program already running
• Fixed overshoot settings not working (they were reversed)

Known Issues

• With hardware version 1.0, results are smoothed too much leading to long response times and reduced overshoot capture

V1.1

Changes

• Added fixed RGB 5 & 10 Offset measurement method

Known Issues

• User settings will be overridden on update
• Test may not cancel if game is closed manually - unplugging the USB cable does resolve this issue but I'm working on fixing it!
