The impressive iCEnhancer visual mod is back again, prettying up your Grand Theft Auto IV. Now it's in 2.0 form, and with a trailer to show it all off.
This one should be easier to get going than before as it's compatible with all patches. As well, if you're paranoid about overheating (and you should be), a more conservative DLL is included.
A 'natural' and more realistic version of the mod is expected to hit very soon, so stay tuned for that as well.
Hit the source for the download, and be sure to let us know what performance you're getting with what specs. If you run into any issues, the forums are here.
