slow lagging even on lowest setting

I have had very sudden issues with coh in that first started with opening contacts and would stutter until i reloaded coh then would be fine but would do it again could be a mission a contact list almost any of the old missions or contacts would set it off. so i reinstalled it and the drivers then could not turn ultra mode all the way up no glow bits no reflective water or parts the shadows were the worst had to not use them at all and no world bit maps as well or higher or again lagg. Thought was graphics driver but again only effected coh all other games fine d&D online ran grate at max settings. Have talked to coh help filed bug reports installed reinstalled every thing from the graphics card to the Ethernet adapter direct x and the game its self completely removed deleted old file wiped with cleaner reinstalled new. And this is were i am now after all this it just gets worse can not even run coh with minimum settings the lag is so bad and looks like lag so please help?

You have a system with 2 GB of memory, running Windows 7 32 bit, along with a video card with 1.25GB of RAM...

You're definitely low on memory. 2GB, in this day and age, is seriously pushing it (CoH is much more comfortable with 4GB). Especially if you're upgrading past XP (fortunately you're not on Vista, which was a bit heavier than 7). You also can't upgrade your RAM without upgrading to a 64 bit OS, seeing as your video card has so much, and the limitations of 32bit architectures.

We've been saving Paragon City for eight and a half years. It's time to do it one more time.

Your video card is not enough for the game.(at least with Windows 7 and possibly the Aero desktop graphics options on)
That is why you get a lot of "Unknown (2147483647)" errors in your CoH Helper report.

The requirements for this game have only gone up over the years due to additions and lack of optimization.
A GeForce 7800 GTX is not enough anymore, especially at the resolution you try to play at(1680x1050). The graphics card is probably overheating at that.


You could try reducing your resolution, for your desktop as well as the game, but I bet you will still have issues playing.
You can also try setting the graphics card fan speed higher manually to something like 70% using this program from Nvidia: http://www.nvidia.com/object/nvidia_...ools_6.06.html
(Edit: You should make sure that version of the software will work for your graphics card. If it doesn't support your card then you will need to likely find an older version.)
You'll need to keep the graphics card temperature under 70 degrees Celsius, using a temperature monitor(there is a windows 7 widget you can find or other software like HWmonitor), for it to keep functioning.

Though, I still think that old card just may not be able to handle City of Heroes anymore.





Edit:
FYI, "lag" is usually reserved for "slow internet", such as is shown by using the command in game "/netgraph 1"(0 to turn it off) in the lower right of the game window.
"Bad frame rate" or "bad FPS", shown by the command "/showfps 1" in the upper right of the game window(60 FPS is perfect, anything below 30 is not so good, and any time it suddenly drops by 10 FPS or more is bad), is what bad graphical performance is. The screen will seem to flash and stutter and animations will slowdown and even stop with bad frame rate.

I'm surprised that Windows 7 works with such an old graphics card. The 7800 is not even DirectX 10 capable, last I heard as I remember, and thus not supposed to be compatible with Windows Vista or Windows 7.
