So since version 2014 I have been using an i7-4790K with successive GPU upgrades. Until yesterday I was using SU2019 on this system that has 32GB ram and a 2080ti GPU. Today I built a new PC and installed SU2020 and opened the same model I was working on before and the performance is horrible, really bad. The new system is a Ryzen 9 3950x, 64GB and the same 2080ti. previous 4790k clocks were typically 4.3ghz, Current 3950x is about he same on all cores. What is going on !?!?

Unfortunately the dumb license rules for SU prevent me from doing that. I had 2019 on my old PC, replaced that with my new PC and installed the 2020 version. Can’t now install any 2019 versions…thanks Trimble, genius move!

[image] PLANORAMIC: an i7-4790K … new system is a Ryzen 9 3950x be aware, that the single thread performance, which is relevant for SU modeling operations, of the Ryzen is only 15% better than the ol’ i7-4790K, therefore don’t expect a tangible performance boost w/ the Ryzen at least during modeling. For the display output speed ensure the SU is running on the GeForce via the 3D program settings of the nVidia control panel (“right-click Windows desktop > NVIDIA…”).

That’s why I pointed out he clock frequencies in he original post as I am aware it’s not going to use the 16 cores I have. They come in very handy on other workloads I perform though. The upgrade criteria was to not perform worse that the outgoing system in single thread whilst offering significant multicore uplift. Ryzen 3000 is about on par with Intel now in IPC so with the 4790K @ 4.3 and my 3950x matching or exceeding that I was expecting fairly close SU performance. The new rig does seem to be getting faster in SU the more I open it and use it though. I am also trawling throughthe settings to get them set up as per the 2019 I had already tweaked to my liking.

[image] PLANORAMIC: Can’t now install any 2019 versions…thanks Trimble, genius move! You could have moved the 2019 license to another machine if you did so before installing a newer version. (This applies to Classic licenses however.) Help (menu) > License… > Remove License… (red button) You may still be able to migrate the 2019 license off of the old PC onto the new one. @colin ?

[image] DanRathbun: You may still be able to migrate the 2019 license off of the old PC onto the new one. if SU v2020 is activated already a previous version cannot be activated on a new system anymore.

Then I agree with the OP, it’s dumb !

Bingo… hence my use of the word dumb. If you want to run dodgy copies its very easy to do so . This annoying feature only serves to annoy legit users.

[image] RfE: make License Data eligible for previous Version(s) Feature Requests for users with e.g. older operating systems or using plugins incompatible with the latest SU version, the license data should be compatible with at least the previous version and at least the same system… in the boundaries of the license agreement of course.

lol, good luck with that one, just keeping the classic version alive is a miracle. Don’t see them changing their stance on this.

I have some amount of super powers, and feel sure that for the next week you will be able to test 2019 again. To avoid running into issues try to keep the number of machines you have activated on as low as possible. That is, a test on one machine may well work, but a test on a second new machine without removing the license on the first new machine is likely to fail. Don’t activate 2020 on any machine before you finish the tests.

SU2020 horrible performance
