I am actually drilling methodically several lines (1...e5 and 1...e6 2...d5 but the question won't depend on that) of the english opening, using ChessBase 15 fast reference search.
The qualifier "fast" is from ChessBase as I am facing really bizarre behaviour, more precisely : I highlight the "Reference" window and start playing moves on the board, and then, even for the first moves (even the very first) I have lags. After the 4th or 5th move the lags are huge and the reference window is really slow to refresh.
Plus, if I change to "Notation" window and come back to "Reference" window then the window is empty and stays empty. I sometimes succeed in making it refresh (and being non empty) by taking back the last move and replaying it, sometimes not. By the way, I am not totally convinced by the fact that the results in this windows are put in some cache so that the whole result in the window is re-searched again. (Yes, really).
Two facts :
- one playing against me : my reference database it a fully up to date Mega Database 2020 with 8.1M games ; I can conceive that searching in a fairly big database can take time (but cache should be used and I hope/guess it is used, but then I don't understand the behaviour I am facing)
- one playing for me : I have a machine with quite aggressive specs : Intel Core i7 7700K CPUs @4.2Ghz, 32GB RAM, 2x GeForce GTX 1080Ti all supported by an MSI Z270 Gaming pro carbon (that I don't use for gaming though, ah ah)
Has anyone experienced such a behaviour ?
