issues with NVIDIA 8500GT

Anonymous — Mon, 25 Jan 2010 06:51:55 GMT

Have been using this card for 2 years; no problems.

Last Friday, upgraded monitor to new Dell 22" screen; checked driver and as it was over two years old (since computer was new) thought to upgrade it to current.

Today, annoying issues when drawing, deleting and working with objects; regularly (but not always) stretchy temporary line on cursor doesn't appear, deleted items don't disappear until i zoom in/out (refresh doesn't do it) and when i open an object and make changes and press ok, object appearance doesn't change until zoom in/out again (even though in the object preview window changes occur as they're done).

Thought the problem may be new driver (nothing else changed except for new monitor) so in hardware manager rolled back driver to previous version; annoying problems still occurring!!!!!

Would appreciate any insight into what could be causing this.

We had pretty much the same issue crop up today!
Try turning 2D Drawing Hardware Acceleration to off!
As infuriating as it was to have to do this, it seems to have worked.

Hope this helps

Thanks for the tip - just fixed the same redraw problem on four of our machines with NVidia FX380 graphics cards running AC13.

When there are redraw problem, it is worth experimenting with other recent drivers, not only the latest one.
One of them may be just fine.
In that case you do not have to turn off the hardware acceleration.

hi Kristian,

thanks for the reply; i did experiment with the hardware acceleration settings but have had no success;
the strange thing is that i've started a new project file (using the AC 13 default template) and can not replicate the problem!!! even with both files open simultaneously and copying + pasting elements between one and the other, the new file behaves as it should (even with hardware acceleration and memory usage set to max, 2d model display set to full model and 2d anti-aliasing switched on), while the same problems are occurring in the old file.

could this be caused by a corrupt element in the project file? it seems to be localised to a specific file.

Hi Bob

I doubt it would be a corruption (but ya never know) but out of interest
check that the same Work Environment profile is used on both instances of ArchiCAD! I managed to accidentally switch something (still no idea what)
in my WE on monday that caused the same issue and when I re-applied my profile it was back to normal.

If that doesn't do it, i'd be tempted to say it could be a corrupt file!
If you need, you can email it over and I could have a quick look at the file here and see if I get the same behavior!

thanks for the suggestion Kristian.

this is weird, but would you believe, it seems to have fixed itself
no doubt something toi do with restart of computer, but strange anyway.
