GTA 4 Game fix

[Nickodzilla]

I Send this the first time to a friend... might as well help the community.

In steam, go to gta 4,setting,property and than launch option...In the box you enter

-availablevidmem 24498 -norestrictions -percentvidmem 100 -noprecache -refreshrate 144 -novblank -heapsize 2097152 -popupwindow -width 3840 -height 2160

since you don't have the same computer obviously you need to change 4 line numbers... -availablevidem(xxx) -refreshrate (xxx) -width(xxx) -height(xxx)

for the availablevidem you'll find it in windows setting under display, advanced display and display adapter properties... it's the dedicated video memory (numbers).

refreshrate its your framerate you want 60fps or wtv youd like.

the width and height is your screen resolution, exemple (width 1920x1080 height).

Now the most important thing is Download: GTAIV.EFLC.FusionFix.zip

You extract it and you place it into the game directory where you see your GTA4 game launching file.

Thats it... you can adjust your screen color and stuff in the game under display and graphic. Have fun.

Thanks, but warning: "availablevidmem" above 1284M or so is not in fact useful since the game doesn't use more anyway -- and PCGamingWiki warns that going over 3G might be an issue in and of itself.

Admittedly I haven't actually seen it be an issue myself (I suppose it may be with also DXVK in there) but again, it's not used anyway so advise here has been to keep it at 3072.0; https://www.pcgamingwiki.com/wiki/Grand_Theft_Auto_IV#VRAM_amount_is_wrongly_detected

Also, you specify "refreshrate 144" and if you intend for that to also be an FPS cap: that only works with also VSync enabled, and/but moreover again: 144 FPS is too much for the game even with FusionFix. FusionFix does solve the worst issues out of the box but leaves another ton of FPS-ssues as of yet still unsolved. See the list at

https://github.com/GTAmodding/GTAIV-Issues-List/issues/112

Advise is to, absolutely, install FusionFix, but to then also use its frame-limiter to cap to at most 60 or 50 FPS; 30 for all FPS-issues.

Another frequent point of trouble is people experiencing frame dips when the Steam overlay is not enabled. Not seen that one myself and not sure what it's about but in any case the advise here has then been to do (only, as much as possible) the 3 or 4 steps from the below:

Things to do on a modern system:

1. Be sure to have/keep the Steam overlay enabled for the game.
2. Add if needed (that is, if the in-game graphics options show only 512M VRAM)

-availablevidmem 3072.0

in the Steam library <game rightclick> -> Properties -> General -> Launch Options.
3. Add FusionFix, as per above,

https://github.com/ThirteenAG/GTAIV.EFLC.FusionFix
https://github.com/GTAmodding/GTAIV-Issues-List/issues/112

and use the then from it in the game's graphics options available frame-limiter to limit to 50 or 60 FPS; 30 for all issues.
4. If you have/use an Xbox One/Series controller, possibly disconnect it, or disable or conversely enable the Steam-specific Xbox controller driver from Steam -> Settings -> Controller.

DXVK is another popular mod, even though it's not generally needed on Windows. Other e.g. texture mods would mean any breakage would need to be on you.

Better one ask Rockstar to refresh their game for newers PC

I'd personally argue that that sort of depends on whether one finds "effective" to be part of "better" or not -- but if you insist...
