OK... tried "Iron". Earlier today, I had a couple meter glitches in the first round (a practice round at SA!), but nothing like I have had in Chrome. Second round (practice at BPB!), I had to run through it quickly, and had 3-4 stutters... bad ones.
Tonight, I played three alt shot rounds ALL METER-GLITCH FREE! Before I started, I set my core affinity to a single core... to the FOUR instances of Iron in my task manager... AND I started-up my GameBooster.
BUT... the weird "chat lag" still happened throughout those three rounds! :(
One good thing was however, each time it happened, it never lasted long enough to bring up the "Shockwave popup". Longest delay was about 30 seconds (which seemed an eternity).
I'm still not ruling-out my keyboard as the culprit in all of this... it seems the faster I type into the chat box, the longer the delays are (when indeed they do occur - sometimes they don't).
I'm also trying to figure-out a way to setup a desktop shortcut to automatically set my affinity with Iron. The quotation marks in the shortcut target line are throwing a wrench into the works when I enter the command line before it.
If anything, I sure am learning alot about using different browsers and I'm getting more proficient at dissecting the inner-workings of my PC by playing this game and thanks to yunz guys! lol :]
