Hi,

Alice 2.6 is lagging badly on our computers. When we click on objects to position them in a world, there is a considerable delay between when we click on an object and when it comes into focus. Also, when we run our worlds that have the arrows control the camera, moving backwards works fine, but moving forward lags so much that we cannot view the worlds in a meaningful way.

What can we do to help correct this?

Thanks for taking my email.

Best,

Was there a recent update to the school Operating system?

The school has monthly Windows 11 "cumulative updates." January's will probably happen next week. When I run Alice 2.5, there's no delay. Is that version still downloadable somewhere?

There are known issues on 2.5 including incompatibility with more recent
MacOS. Here is the last available 2.5 build on Github:
https://github.com/TheAliceProject/alice2/releases/tag/2.5.4

thanks

Subject: alice-teacher Alice 3 is lagging when using the Move handle tool
Message-ID: <F90775EB-BA31-4D22-8032-487A88B9574E@sxu.edu>

I have been having a lot of problems in class with Alice lagging to the point of being unusable. This started last year, with Alice 3.8 (I think). It is hard to reproduce, so I haven?t reported it before now.

Switching between selected objects causes a slowdown when using different handle tools, especially the Move tool.
I have seen this problem on several different Windows computers, but it is worse on some, depending on the graphics card and the CPU, maybe. It seems to come up after using Alice for a while, so maybe it is a memory leak.

It makes Alice practically unusable. I tell students to avoid the Move tool and just use one shots.

Steps to reproduce (maybe):
1. Add some objects to the scene, and move them around.
2. Go do something else for a while (leave Alice running).
3. Switch back and forth between the tools, particularly the Move tool.

Alice lags. It can be a few seconds, up to 60 to 90 seconds or more. It will eventually respond, but you can?t keep waiting a minute every time you switch objects.

We have a lab of Intel Core i5 machines, 16 GB RAM, Windows 11. The graphics card is Intel UHD Graphics 770.
