The upscalers start on a 3440x1440 screen (issue #13, a second report). Checked on the test host with the geometry from the reporter's log, not yet in a game.
- A 3440x1440 screen (and any window drawn a pixel or two smaller than its frame): the upscalers start. Issue #13 (a second report): with Transport Fever 3 on a 3440x1440 monitor the log said "frame 3440x1441, output 3440x1440 ... input viewport 0,0 3440x1441,
output viewport 1,0 3438x1440 ... they do not fit together; NIS stays": Lossless Scaling draws the window's 3440x1441 into 3438x1440, a shrink of 0.06 %, and the upscaler only took an output at least as big as its input. An output up to half a percent
smaller (at least 4 pixels) is now taken as 1:1, the input trimmed evenly on both sides to the output's size (within a pixel of NIS's own picture at the very edges, exact in the middle). Host scenarioscaler_crop_3440.
