OP your timing couldn't have been better. After purchasing this the first time it went on sale I've only just downloaded it to officially start playing. Thank you!!
Really looking forward to playing this, the YouTube vids are breath taking. I've installed the mod and played for a few minutes and it really looks phenomenal with an average of 44FPS.
For anyone attempting to try this mod on their Steam copy, I can confirm that the mod installs and works without issue when steam is fully closed down.
If this it's of any help then here is the process I used for my first time install:
1. Turn off steam
2. Make a duplicate copy of the GTA game directory
3. Check exe version number, mine is 1.0.7.0
4. Download the patch from
this site
5. Extract the file and read through the readme
6. Copy from the referenced files into the GTA IV folder
7. If you are not asked to replace files then you have copied into the wrong directory
8. Run the LaunchGTA exe
9. It will state that an xlive.dll is missing
10. Go to installables folder
11. Install the GFWL and the VisualC files
12. Try running LaunchGTA exe again and it will start
13. It will ask for your CD key so close down the game
14. Start up steam and go to your library
15. Right click on the GTA IV game link and choose CD key and note it down
16. Fully close the steam application
17. Run the LaunchGTA exe
18. Enter the CD key and now setup your graphics and run a benchmark
19. When secuROM asks you to log in, just choose play offline
20. Yay deal with GFWL... Log in, download profile, download update, restart game, log in and enter CD key
21. Enjoy the game
Don't forget your manners, if this helps you then say thanks.
