Hey guys,

I don't know how many of you know about Large Address Aware - it's an application thanks to which programs can use more than 2 gigs of memory on x64 systems. Quote from original topic on techpowerup.com:

This is an application that assists in making applications large address aware. When a 32-bit application is Large Address Aware, it can access up to 4 GiB on x64 operating systems and up to 3 GiB on x86. 64-bit versions of Windows require no modifications to the operating system to benefit from this application; however, in 32-bit versions of Windows, you must increase the user memory setting.

So, how does this apply to GTA IV, you ask?

Wonderfully!

After applying the LAA flag to GTAIV.exe, my game is much more stable. It might be just a placebo effect, but it feel smoother, textures pop up faster and it crashes less (from 15 mins. to about 30 - 45).

Link to the application and instructions how to use it are here - http://www.techpowerup.com/forums/showthread.php?t=112556.

It also works with other games!

Just remember, you must have x64 Windows to use it.

Try it out and let me know if it worked for you!

checking this out right now.

 

thanks for posting

So this makes GTA IV more stable and run with better FPS? OR just be more stable?

For me it increased stability and get rid of texture loss and some FPS drops, but it didn't give me more FPS.

The results well surely differ on each PC, though.

Thanks, could be helpful for a lot of people.

 

Although, in the forums, they say "Large Address Aware won't work on applications with security features that perform a checksum on the binary.".

Isn't the case of GTA IV with the Securom security ?

 

Damn it! I can't use this, I would of loved to give this a try.

 

Trust me to have 32BIT software.

 

 

No, because it's LaunchGTAIV.exe business. The game itself it's GTAIV.exe (that's what should be patched with LAA).

Ok thanks :)

I'll try this later, I don't have issues but I want to see if it reduces a bit the clipping and other little crappy things due to the bad work of Rockstar Toronto.

I'll have to give it a whirl later then. I get texture loss oddly frequently, not a whole lot, but enough to get on my nerves. I know why I get them, but if this may help cut down on that, I'll be a happy camper!

It works amazingly for me. Spots where I used to get an FPS drop don't really have effect anymore and the game does, as you mentioned, run smoother. Thanks!

Well, I don't see changes, but it's normal I guess, I didn't have big issues.

+1 for the topic, because it seems to help a lot of people. Thanks pony buddy.

Well, two people are not a lot :) But thanks.

thanks for posting this.  Went from being able to run on medium settings at 30-35 fps to running high settings without losing fps.

EFLC already seems to have this flag set. Maybe that's why people have found it to be more stable?

Thanks for posting the program Yard1.

I just hope now ELS V7 doesn't crash the game while it is loading or 3 seconds after I appear in the Broker Safehouse.

 

Cheers.

Really helps a lot! Thanks for posting!!

tried it...really an improvement for me

 

+1 for ya

Seems to work for EFLC.

My GTA IV worked great performance wise for quite a while.   Then i added game4video and els 7 and started getting 30%-40% FPS drops and that introduced 25% more crashing.

 

 

I didnt expect anything from this but it worked amazingly for me.    I am pleasantly surprised..   It is more of a 20% fps drop but manageable and it doesnt break the  gameplay immersion as much.   And i do not get early game crashes at all anymore(knock on wood).  I only have seen crashes now when i play for a long stretch of time and have like 10 ELS cars on my screen for a while. 

 

I would REP+ you up twice but i dont think i can do that.   :D

 

 

Cheers,

Wow, I didn't except that it would work so great for so many of you! Glad to be a service.
