So you have re-downloaded the game and still receiving CTDs with ENB? Does your game work fine without ENB? What are your system specifications? Do you have any on-screen-display software running like MSI Afterburner?

I'm definitely going to try this! Thanks for sharing.

OpenIV

I know for sure that Vucko 6.0, Game4video and ChineGreenElvis ENBs are working because I used them before. So I think you should do a clean installation of the game because maybe you installed something and it messed up the game, since you are using steam version updating stuff is not going to an issue. If you have more HDD space you should backup the whole game just in case you get that kind of problems again.

Maybe InjectSMAA is crashing your game?

Did you deleted/reinstalled/renamed/moved GTAIV recently?

Do you have a backup version of GTA IV?

Which ENBs you have tried to install?

Are you using Windows 8?

Mount .iso file with DAEMON Tools or any other optical disc authoring software.

But you haven't posted diagnostic report.

Try those simple solutions: Make sure you aren't using a crack - We don't support cracks Update GTA IV to 1.0.7.0 (the latest version of the game, or 1.1.2.0 for EFLC) - This sometimes fixes a wide variety of issues Make sure that you run the game as an administrator. Make sure that your GTA IV root folder (and every subdirectory) is not set to "read-only" Ensure that FirstResponse.net.dll is in the SCRIPTS folder and that AdvancedHook.dll is in the GTA IV ROOT folder. Ensure that ScriptHook.dll, ScriptHookDotNet.asi and Dsound.dll OR Xlive.dll are in the GTA IV ROOT folder Ensure that there is a folder titled 'LCPDFR' in the SCRIPTS folder. Check that all the above files exist, if they do not, reinstall LCPDFR with the automatic installation. Ensure that you are using up to date versions of every LCPDFR dependency and LCPDFR itself.

From 01:15 to 01:24 and 02:22 to 02:46. http://www.youtube.com/watch?v=U1Qe8D0ODSg

Try to re-install the game.

Try this: http://www.gtaforums.com/index.php?showtopic=384614 Do you have installed Service Pack 1 and latest nvidia drivers?

Go to nvidia control panel > manage 3d settings > select GTAIV.exe > click restore.

Very strange for sure. You could and try disable Clip Capture, and you can also reboot your PC if you haven't done that already.

Hmm..you could try patch the game to 1.0.7.0(GTA IV) or 1.0.2.0(EFLC) if you haven't already.

But you haven't posted diagnostic report.

I also forgot to ask, what specs do you have?
