Water Lag?

cryforme

<div class="IPBDescription">only happens in certain maps</div> I have found that on maps with a lot of areas with water, such as daimos, altair and in certain places on other maps (near MS on hera) i get massive lag, choke to 99, loss to 50+ and my fps drops to around 5. I'm on cable, have all my rates and settings correct (using old CS rate i got from a rate calculator, as well as recommended updaterate and cmdrate settings), i have my fps_max set at 99. Running 1024x768 on an intel extreme graphics onboard, 3.2 ghz proc, 2gb DDR. i shouldnt be having this problem as far as im aware. can anyone lend a hand?

Integrated graphics? May be the problem right there..
