Hello community,

I recently started four-boxing again but I am having an fps issue. Here is my setup:

My setup:
ATI Radeon HD 4870x2 (disabled 1 gpu)
i7 920 2.67 Ghz
6 GB Memory
Intel 80GB SSD

As far as I know there should be no problems with my setup, but I am not sure if one, or more, of the parts are malfunctioning. I am having great fps when running around alone, but as soon as some heavy particle effect hits my screen my fps drops to around 5 fps, and it feels wrong. 4x Thunderstorm makes my fps drop from 40 to 20 for a few seconds. I've also noticed that my fps drops a lot when entering towns to around 20 fps (from 40), and it never used to irritate me, as it does now.

Using ISBoxer+Innerspace, and foreground fps is limited at 40, while background fps is limited at 15. Two monitors with one client being 1920x1200 and three clients being 480x300 (kinda small).

Windows 7 was re-installed not long ago and the os is in pretty good shape and not bloated at all. Drivers are also up-to-date. I am aware that 4870x2 can get pretty hot, but I've tested if that was the issue, it wasn't.

My point is that my setup doesn't run smooth at all, even though it should run pretty stable. I am wondering if you have any ideas, or what I should try to replace first? Hardware or software related?

I am stuck, and don't know what to do here. Thanks for the help ;-)
