WTF?!?!? What do you guys normally leave your scene selection on? What exactly does game mode do and will I sacrifice anything else if i leave it on 24/7?
When game mode is selected the options in picture setting for noise reduction, mpeg noise red, Cinemotion, and motionflow are greyed out. But this obviously doesn't do the same thing as just turning it off when using other scene selections. There must be some other processing turned off as well.
So it's not the receiver after all.
I played gta with game mode on and it made a difference with input lag. Its still no where near as responsive as a mouse. It's not real time, so to speak. But it is a good bit of difference. Man, I loved the look of the cinemotion. Oh well.
I realize this post is a little old but I haven't been on AVS in a couple weeks and I see you still have the TV.
I just went through this, albeit with a different TV (Panasonic E60). I had an older Yamaha receiver that did not have HDMI passthrough so originally I put all HDMI devices into the TV and used the optical out to the receiver. There were NO audio sync issues with any content at all. Later I realized that Panasonic in their infinite wisdom, opted to not support dolby digital output from the optical cable when using an HDMI source. So I ran the optical from each device directly into the receiver and kept the HDMI video into the TV. However, once I did that - horrible audio lag. Fast talking TV shows on the TivoHD was like watching a chinese dub. It was so bad. All sources had audio sync issues - PS3, TivoHD, cablebox - some looked worse than others because the content kind of hid it, but it was all there. The audio would arrive before the picture across the board. Turning on Game mode on the TV solved the issue but only because it essentially removes all TV processing. The picture was not nearly as appealing in game mode. The issue is really that the TV takes time to process the input and the receiver is getting the audio instantly. When run through the TV, the audio was in sync because it wasn't sent to the receiver until it was done processing. Unfortunately my receiver did not have any options to set a delay to compensate for that. Modern receivers however gave the option for auto lip sync via HDMI 1.3 or setting the audio delay manually. So my only recourse would be to live with 2ch sound or get a new receiver with HDMI passthrough and audio delay or that supported HDMI ARC from the TV. I also looked at exchanging the TV for the Sony 550A but given that it was a $500 price jump, I opted to go with a new receiver for $400 - the Yamaha v673.
Once I got the receiver I put all my HDMI devices into the receiver and one HDMI cable to the TV. Originally I left the audio delay to "auto" and it was GREATLY improved across the board without the TV in game mode, but I used the Disney Wow disc's test for audio sync and fine tuned it to 90ms. Since I set that, I have no noticeable audio sync issues. Now I haven't played any games yet but when I do and I turn the TV to game mode, I'm going to have to turn off the audio sync for that input so I don't end up with audio BEHIND the picture.
Either you need to set the audio delay on your existing receiver or if you don't have that option, you will likely need a new one. Personally I'm happy I was "forced" to upgrade. My new receiver is leaps and bounds better than my ~8 year old Yamaha. It was a year of HT upgrades lol.
