ATOMICC Computer Testing Blog has run several matches pairing Vitruvius against several well known engines:
1 Vitruvius 1.11C HEM x64 1CPU +53/=40/-7 73.0/100
2 Fritz 13 +7/=40/-53 27.0/100
1 Vitruvius 1.11C HEM x64 1CPU +25/=54/-21 52.0/100
2 Critter 1.4a 64-bit SSE4 1CPU +21/=54/-25 48.0/100
1 Houdini 2.0c Pro x64 1CPU +37/=44/-19 59.0/100
2 Vitruvius 1.11C HEM x64 1CPU +19/=44/-37 41.0/100
1 Rybka 4.1 SSE42 x64 1CPU +25/=59/-16 54.5/100
2 Vitruvius 1.11C HEM x64 1CPU +16/=59/-25 45.5/100
All engines use 1 CPU.It would appear that this is a very good engine, but not quite up to the level of the very best. On the other hand, if it does play ‘human-like’ as the authors claim it could be, for a lot of players, an engine worth investing in.
