I know I'm gonna get shit for this : Bought a new rig q6600, 3gb with vista home32. Bought over last weekend, problem has persisted since monday. Noticed TWS quotes are laggy (ie. I see a lot of the yellow 'stuck' quotes) before they update to real time when switching pages in TWS. Main problem though, is that at times TWS charts aren't updating in real time. I trade up to 6 underlyings, I do trade into news events, and not having the chart update is suicidal. The chart quote works fine, just the chart doesn't update. Tried dumping java cache, didn't work too well, problem came back. Rig is setup for trading only, all extra features turned off and security jacked up. Can't find a problem with security not letting data in, not all 6 charts don't update. 3 charts seem to be fine, but I trade off mutiple correlations. Old rig had no problems like this, a bit slow to switch timeframes/load charts but no actual delays. Old rig was XP, pent4HT with 1gb. I have several options : 1)switch to XP 2)force 1 processor to commit to TWS only ( no idea how to do this yet) 3)relax security (not to keen on this) Thoughts?
