Bad graphics quality in drawing mode but fine in design mode

[barryQWBNZ]

When I make a drawing I experience very bad graphs: Broken lines with random pixels around it. When I''m designing a part the graphics are just fine. This does me believe it's an Fusion problem. I've attached screenshots. 

Windows 11 and a nvidia gforce RTX3060

Hi,

just try another driver setting

I tried all three (DirectX11, DirectX9 and OpenGL). All give the same bad graphics for drawings. 

It's annoying as it makes it hard to select the features to add dimensions.

Hi,

I think @ClintBrown3D  can say something about that.

Hi @barryQWBNZ 

Sorry to hear that you are having trouble. This certainly looks like a graphics problem.

If you are running a dual graphics card on a laptop, then you will need to do a bit of additional setup. Windows introduced some changes to the way graphics are handled. Your NVIDIA control panel no longer controls which apps are assigned to run on the main GPU. I've put together a quick guide to setting this up here: https://clintbrown.co.uk/2022/07/27/troubleshooting-dual-graphics-cards-on-windows/

Another thing to try, is to download the latest graphics driver for your card from NVIDIA, they generally push our updates every month or so.

I folllowed the guideline for the graphics settings. (I do believe Fusion was already using the nvidia card looking at "graphics diagnotics" in Fusion). 

In the mean time I also got a windows update and a Fusion update. 

But the good news is that the problem seems to have disappeared. 

Thanks for the support!

I followed @ClintBrown3D 's guide, but Windows 11 is slightly different. It allowed for a huge improvement in the graphics quality for a section view, and then I tried another in the same drawing, and it didn't work.

Any advice would be great. Attached is a screen capture of both section views that are in the same drawing. 

Note: if I try to replicate the section view that looks good, it looks rubbish. It appears to have only created a decent view that one time.

Update - 

The assembly that I am trying to do section views of is a wiring loom with 23 unique components (33 parts in total), some are wires that are 4m long.

When I reduce the size of the section view (to just less than is useful to show what I need to show), it renders nicely. When I have the section view large enough to show all of the parts I need to, some of the part colours disappear, and the colours that are left look as if they were coloured in by a 3 year old with a crayon. 

The only thing I haven't tried yet is updating my gpu driver, as I am awaiting a call back from my companies tech support to do this.

If anyone has any other ideas, it would be great to hear them. Normally I would produce line diagrams that do not include colour, but with different coloured wires and connectors, there is a huge benefit of having the colours on the drawing.
