Open GL question

Tom Krowka — Thu, 25 May 2023 15:03:54 GMT

I have had some problems with very distorted 2d drawings; the circles being segmented, diagonal lines that look like a set of stairs, other lines not going where they were when I closed the program. This will usually happen when I open AC9 at various times.

After changing settings on the display for half the day, thinking it was a video card problem, by chance I changed a setting in the "2d Redraw Options" in the user preferences in the work environment.

I turned off "Optimize drawing method for high performance display card (Open GL)". The 2d drawing immediately went back to normal.

What did I do there? Does this mean the OpenGl is not working for the 2D only? I thought it was supposed to be so much better.

Any insight would be helpful. I am using a GeForce 4 128 mb agp4x card. I did the compatablilty test with it and it worked OK, no major problems except some text fill issues. Also, a pentium 4, 20GHZ intel chip, plenty of memory on the hard drive, 1 gig of ddr ram.

Thanks.

Thanks.

Wow, can I get one of those 20 GHz machines? Must be expensive, though...
Sorry... Could not skip it...

To reflect to your issue, I also experienced OpenGL problems in 2D and I actually do not use it at all.
If you uncheck that checkbox, OpenGL will not be used in the Floor Plan Window at all.

German users of ArchiCAD 10 already have those 20Ghz machines.
Just to open the file.
