I only had the VPL-HW50ES for a short period of time, and I would have liked to spent more time with it, but I thoroughly enjoyed every minute I did get to game on it. The color was amazing, the contrast was amazing, and the shadow detail and black levels were amazing. I would go as far as saying I like this projector more than my own Epson 8700UB. The lag test
determined that it had about 50ms of lag, but after the review I realized the CFI feature was on when the lag test was done. It should yield much better results with it turned off. As always, here's a link to Art's full review
While I had the projector I played Street Fighter IV on the PS3, Borderlands 2 on the PC, and Half-Life 2:Deathmatch on the PC. I did not notice any sort of lag while playing online, or off. I haven't had my hands on one of the new Epson projectors, but based on what I have seen comparing the Epson 8700UB and this Sony, I would pick the Sony. Street Fighter IV looked amazing, and this would be a game you'd definitely notice if lag was an issue.
Even with the projector testing at 50ms, I never noticed it while playing. This projector performed amazingly well for gaming, and was visually better than any other projector I have reviewed (my wife even approved). I felt totally immersed in the games, more so than ever before. I can't speak highly enough about it.
There wasn't much I disliked about the Sony, so let's get to the meat of things.
Great black levels
Great shadow detail (very important for gaming)
This is a big one, so forget about portability if that is important to you.
Is it a bit pricey for most of us gamers at $3,999,99 MSRP, but well worth the cost.
I've got nothing! There is nothing ugly about this projector.
