thanks for the tips -- wasn't aware of the performance hit, but i am very aware of the large pages issue/s. i may disable score main move as i can't say i notice any more frequent updates than with R3.

I was thinking about the information that we gave when we put the results of test
positions, many years ago: engine, processor, gui, hash tables, tablebases, etc..
Today is different, few are concerned with these details. Why?
These details, in my opinion, remain important, especially
for developers.

Not really. Suppose I tell you engine X solves your position in 1 second, and I paste the info and nothing else. It makes a difference whether I am running it on an 8-core box with 8GB hash, or a Pentium III running at 500 MHz, no?

An example: I remember Bob Hyatt spoke that the greater the amount of HT, better for the endgame.
