Thank you for that replay Jim. I found a way to use 4gb with NVSE Ok i got the solution..get you kudos giving finger ready : ) Make a shortcut to f4gb.exe to your desktop. click that then, edit properties --> go to shortcut tab and then look in the "target" box. Mines looks like this: "C:GamesSteamSteamAppscommonfallout new vegasfnv4gb.exe" Edit that line, at the end put a space and then "-nvse_loader.exe" without quotes at the end of the last line of text in the target field. Now it should look like this: "C:GamesSteamSteamAppscommonfallout new vegasfnv4gb.exe" -nvse_loader.exe Save and close...launch through the fn4gb shorcut on your desktop. Ingame open the console and type: getNVSEversion it should return: NVSE v.1 p.s. You're welcome. This post was edited by streetstar5 at 08:45, 6 November 2010
