TopFlite,
I could be a myriad things. I had tried every browser under the sun and I thought every tweak to my graphics card. Had no luck with any browser Oct and Nov. I ended up disabling my graphics card and running solely off the integrated chip. Meter doesn't stutter now but freezes and rocket balls happen more frequently.
As for Jason's post, by all means try Maxthon. It's the only one other than Pale Moon x64 that will remotely run the game for me personally. Firefox used to be pretty good but I've never had any luck with Chrome, even using the suggestions/ tweaks from WGT as their preferred browser.
NOTE TO EVERYBODY CONSIDERING A LAPTOP PURCHASE......stay away from Sony Vaio. Mine (1 yr old) had very good reviews and outstanding performance metrics but I've had a giant headache with mine. Sony laptops are very particular about driver updates and I get more "incompatible" error messages trying to update my system than you can believe.
Case in point, I tried to create a dual boot with XP on the other partition. This is not hard to do and I have done it several times on other brand computers. Not so good on Sony. It fried my hard drive and I lost everything.
