Hi Dariusz,
Default behaviour with Root is to use True Type Fonts.
If for speed reasons, you have disabled the TTF, you can improve
the quality in case of labels in small windows by selecting hardware fonts.
For example, do:
gStyle->SetCanvasDefW(400);
gStyle->SetCanvasDefH(300);
gStyle->SetLabelFont(60,"X");
gStyle->SetLabelFont(60,"Y");
TH2F *hr = new TH2F("hr","font test",2,0,1,2,0,1);
hr->Draw();
See TAttText for more info on the font precision/quality/speed.
