I have a strange problem. I've been using Chessbase for 20 years and currently use Chessbase 16. On my main computer, I have 32 threads. I can open Chess Base and set Stockfish to 32 threads without lag. I tried doing this today with nothing else open and was getting lag. I tried a different chess engine with 32 threads, and still had lag. I opened up Fritz 17 and used both engines with 32 threads without issue.
I then tried my laptop, which has 16 threads. I had the same issue with Chess Base 16. I did not have any problems with Fritz 17. I can't imagine it's any change I made because I haven't made any changes. I also need to find out how it could affect two different systems. I would be grateful since it's easier for me to use Chess Base.
I'm stumped. I tried to roll back the drivers, but it did not fix the issue. I used Win 11 and Win 10; my main desktop and laptop had AMD chips. I even bought it on my old desktop with CB 16 and Fritz 17. It is using Win 7 and an old I7 3770K. On the entire eight threads, it lags on CB 16 but not on fritz 17.
I have tried the new CB 17 and still get the lag issue. Immortal was always the best, for finding help. Thanks in advance for it!
Maybe in CB16 under options Engines the parameter Intelligent CPU-use is activated? Then not all threads are activated for the engines. Just check this possible cause of your problem
Fritz says we are using 32 threads and I am getting good nodes. CB 16 says its using 32 threads the nodes look ok but it keeps freezing
