Why Affinity Designer 1.7 uses with 25.9 more GPU that 1.6.5 ?

Recommended Posts

I know is from GRID but i have lag in 1.7 with 131% zoom. In 400% is impossible to draw.
But why uses so much only to draw a perfect pixel ?

In 1.6.5 i have lag only after 400% zoom. In 1.7 all time.

And when the Zoom will be with Pixels without decimals ?
I say this in other request because the Grid Lines is misalignment with the Transparent background pattern.

Sad :(

I try the latest beta and my Intel HD Graphics is 100% with Grids ON.

Preset: 1920px - 1080px
Zoom: 73.2%


Without GRID:

In Maximum total CPU 40% and (GPU 55%)
In Maximum total CPU 45% and (GPU 56%)

With GRID:

In Maximum total: CPU 55% and GPU 96%
In Maximum total: CPU 27% and GPU 100% - Bottleneck


Mo much difference in both without GRID.
Now i don't have a dedicated video card but why the Grid in 1.7 is making me Bottleneck and lag ?

Hmm that's weird. I've never seen such high GPU usage.
Mine always stays less than 10%...

I thought Windows version does not use GPU like Mac version.

I have the integrated video card from Intel. Intel HD Graphics 4600, is not compared to a dedicated video card. But that GRID use +55% more GPU when paint...
And in the 1.7 is impossible to paint with it ON. In 1.6.5 is still very smooth if is with 95% GPU.

I make a custom grid with Rectangles and the Performance is the same like Without GRID.
I think the original GRID is redrawing every time you PAINT, scrolling. Not only when you use ZOOM.
Why is that difference with GRID ON and the custom GRID with rectangles, really i don't know. No impact to GPU at all.

I don't have this problem with either Designer or Photo. Zoom to 400 or 800% and no lag at all. 1.7 retail or beta. But this is with a dedicated graphic card.
