While we consider the AT&T HTC Titan an excellent Windows Phone (here's our review) it has a quirky graphics lag or stutter at times. The stutter occurs more often with apps that have heavy graphics (Fruit Ninja is a good example) but it doesn't happen constantly throughout the game. Just enough to be noticeable.

WPCentral reader ElecktroDragon has discovered a temporary work around that eliminates the lag time and may identify the problem as being related to the Sound Enhancer Setting.  If you go into the Titan's Settings and turn off the SRS Enhancement in the Sound Enchancer setting, the lag goes away.  Based on the forums discussion, sound quality is just fine for the games without the SRS turned on.

While this seems to do the trick, it also means that for the time being you'll need to go back into settings to turn back on the SRS Enhancements when watching videos or listening to music to enjoy the sound enhancement.  We're still hoping that HTC can resolve this issue with a software update but in the meantime, at least we have a temporary fix.

Edit: This fix/workaround also applies to the HTC Radar/Radar 4G

Thanks goes out to ioannisgk for pointing this out.
