Thanks Steven. I just set animation speed to 0 and it's less bothersome. I appreciate the Mac build as there are not many quality chess apps and ScidvsMac is one of the, if not THE, best!
SCID vs PC

You can try replacing the Tcl and Tk Frameworks with the Wish-8.6.4 frameworks. (found here https://sourceforge.net/projects/scidvspc/files/mac-64bit-unsupported/ I think there is instructions in the tarball). It works better for me on my Mojave system (though of course i run the 32 bit Mac app mostly) - engine responsiveness and animation are both better iirc.

I updated the wish framework. I don't see a change in the animation, but I'll watch to see if I notice any other improvements elsewhere.

Ok... but just make sure they are installed properly into the ScidvsPC App, and the about window says
"Using Tcl/Tk version 8.6.4".
It's not straight forward. I love my old Macbooks (though my main desktop is Linux). It's just so much effort to fight Apple (and the core Tcl/tk team) who put everyone on the hardwarwe upgrade cycle. Once upon a time Apple said they'd support a 64bit Carbon Framework going into the futture, but realised they'd sell more computers if the obsolesce things, and pulled the plug when the software was almost fininshed.

Hello, I have been trying to import custom pieces into SCID. I am running a Windows 10 computer, and the files are already in .svg form and are in the /bin/pieces folder. However, whenever SCID starts up, it displays the message in the startup window:
True type fonts (PGN figurines) disabled.
User Pieces: reading C:\Scid vs PC-4.23\bin\pieces
Loading file bb.svg failed
Loading file bw.svg failed
Loading file kb.svg failled
etc.
Then everything afterwards works as usual.
I dont know why its failing to load the .svg files, does it have something to do with the "True type fonts (PGN figurines) disabled" message?

I would like to add, I have not configured SCID in any way at all prior to this. I had simply downloaded and opened SCID, closed it, put the .svg files into the pieces folder, and then run it. Therefore, there might be a step that I missed that I simply didn't know about.
I am trying to configure SCID vs PC on Fedora Linux.
I added stockfish and lc0 engines, and cassia db no problem.
When I try to play vs lc0, if I go out of book the engine does not play any moves in response.
What am I doing wrong? Stockfish seems to be able to play out of book.

I believe that lco for Linux has to be compiled from source (which I've never done).

What videocard you are using?
Also notice that you have to allocate plenty of RAM to the engine, as Leela keeps the entire search tree in RAM.

You'd better use stockfish, which is hassle-free, and also arguably stronger.

I have stockfish working, would like to get both working OK.
No GPU here, I compiled using the OpenBLAS version.
I don't remember allocating any RAM so I'll take another look at the options, thanks.
Steven - I opened 2 tickets against version 4.22 (Debian linux) recently before I realized there's a 4.23. The 2 tickets are about copy/paste problems with the PGN comment editor. Any chance these issues were addressed in 4.23 (or will be in an upcoming version)? Many thanks.

Why would one choose SCIDvsPC over "plain" SCID? Are they both still under active development ?
Yes, both are, although SCID gets a new version less frequently, actually development had effectively stalled between 2013 and 2018.
They are similar by design, but they have several functionality differences. I am sure the differences were posted somewhere in this thread, but I'm just too lazy to search 1050+ posts...
personally, I prefer the vs PC stuff, but I could also live with SCID
Anyone know how to add moves by means of successive copy-and-paste, like from a PDF source for example? I have not found a clean and efficient way to do this. To add to an existing mainline I "paste variation" then go to the PGN window and "promote variation" and finally "delete variation" (the stub left over by promotion). This is all very cumbersome, it seems like there ought to be a "paste mainline", but I don't see anything like that:
Am I missing something obvious? If SCID vs. PC can't do this is there another app that allows this in a convenient user friendly way? Thanks.

^^^^ The only way i can think of doing this is by control+shift+i to open the import pgn text window, then "Paste current game", and edit the game in there with copy and pastes.

I just posted a new forum about Scid vs PC and eboards. Replies over there would be great. Cheers

> on Catalina. Animation seems "bouncy".
Yeah - known issue - it's just buggy :(. I've had some feedback that this is not an issue on the latest macOS, but I'm not testing it myself as new macOS is a bug highway imho.
