Multiple instances of AC18

[Anonymous]

When I use 2 instances of AC 18, both of the run very very slow, or freezes. Please help me, what is the problem ? In AC17 worked well, but in 18, not !

The problem was the Geforce Experience software that comes with the driver.
Uninstall it solved the problem.

YES!
We've been tracking this problem in several places. I had no luck with the IPC fixes, but uninstalling GeForce Experience worked brilliantly for me. This software installs with the NVidia driver seems to be an interface for game display tweaking. It can be uninstalled without affecting the general display at all and totally resolved the multiple ArchiCAD issue for me, even with my wimpy 4 GB RAM.
Many thanks Edcad!

Thanks for this. I was about to go back to Archicad 17! Like usual the first release is going through growing pains! Much to the frustration of it's users!

Going back to AC17 wouldn't solve the problem. I tried it and was the same with the nvidia experience software.

ON PC ! It is not about processor or RAM i think. I have I7, 8 GB RAM. Every time i open the second instance (to copy something from another project) it freezes. Than I have to quit both ArchiCAD instances and open again one instance.
Ac 18 is the most buggy version i've seen ! Please make some updates.

What is your graphics card? If it is a NVIDIA have you tried to uninstall the experience software?

Thank you very much! This actually worked for me! I'm running AC17 on windows7 with Nvidia. Seemed that Geforce Experience has been causing the problem. Terima kasih again
