Skuzzy:
I checked my options->graphicdetail->advanced->max texture It was set at 1024.
I have now set it to 512, which is the lowest it will allow me to. I will see if this helps.
Im experiencing the lag in more instances during the game,I've now noticed it in the cockpit over airfields a lot recently. Smoke/flames are present at all times when I lag.
I'll play for awhile at 512, but there is not a 256 setting that I can select.
thanks,
Rot
Rot,
that's not the setting that Skuzzy is talking about,on the startup page were you select online/offline you will see a "video settings",select that and adjust the maximum texture size to 256 there. You also might benefit from a reduced resolution,less pixels to move around.
I'd experiment with 512 at a lower res VS 256 at present res and see which works better.
Another thing to check when you're experincing this lag,right click on clipboard map and select "net status",look at top graph it should have a straight line,if the line is sawtoothed then you're having internet issues.
YMMV as I will bow to skuzzy's superior knowledge in these matters.
hope that helps!

PS: you might consider a better vidcard!
