Cursor Response time on 4K monitor

[James108]

Hi
I have discovered a performance issue in NT8b5.

When I have chart maximized on my LG 31MU97 4 K monitor. The cursor response time is very sluggish. If I move a horizontal line quickly up and down CPU usage gets up to 15%

If the chart is just a portion of the full screen, then it seems fine.

On NT7 this is not an issue it responds very well even at full 4096 x 2160

I'll have to try moving a line on my 3k and 4k laptop with a full size chart.

Are your crosshairs fine with a maximized chart on that 4k?

Are you using hdmi displayport or mini displayport?

Cross hairs have the same issue

I am using the supplied DP cable, mini into the monitor and regular into GTX 960 NVidia card

Here is a video of what happens when I move a horizontal line up and down when the chart is maximized.

IT should be noted that grey line is with the crosshairs on. Took me a while to figure out what it was.

Yes, the Hardware rendered graphics have been a little problematic.

I do see the same lag on my laptop 3k screen, nvidia quadro k3100m or intel hd4600?..

It's palatable...definitely not optimal in any case.
