IsoDraw new GPU cracked drawing in 2D when zoom out

Hello,

 

We start IsoDraw 7.3 M080 on our new NTB with Nvidia Quadro P600 and we have problem.

 

When I have drawing in 2D and go full page display (zoom out) the drawings get cracked.

 

When zoom in it works nice and fast.

 

We think problem is here with 2 GPU so we turn off integrated GPU in bios.

 

Problem is something like GPU wont work when display is bigger, somethink like saving off power.

 

Does anyone know where should be problem ? Thank for any messages.

 

Thank you. Full page - zoom outFull page - zoom outZoom inZoom inRedraw settingsRedraw settings

I found a solution for an issue that sounds like yours.

PTC recommended that we disable OpenGL (which also disables Anti-Aliasing).

We did not like how this looked.

I found that the nvidia driver settings, when set to prefer "Quality" were on the low end of what our graphics cards offer, so I cranked the setting to 11 and the problem disappeared.

The biggest change came from FXAA (which is disabled by default) - enabling it immediately solved the problem, but all the lines appeared stronger.

We opted to leave FXAA disabled and instead set the Antialiasing to "64x (16xSS, 4xMS)"
