This happened randomly during a heist. I have restarted the game but it doesn't seem to work. Does anyone know how to fix this? Thanks.

UPDATE: It self fixed, but hell was it funny when it was going on.

Grand Theft Auto IV is notoriously one of the worst PC ports in gaming history. If you try to run it on modern integrated graphics—like an Intel HD 620 on an office laptop—the game will stutter, lock your video memory at a useless 512MB, and lag violently.

Even modern optimization mods like FusionFix can accidentally tank your performance because they introduce heavy graphic effects intended for high-end gaming PCs.

If you want to achieve a perfectly smooth, stable 30+ FPS experience on a budget laptop, follow this definitive step-by-step optimization blueprint.

### Step 1: Fix the Broken Video Memory Limit

GTA 4 completely misreads shared laptop RAM. We need to create a text file to force the game engine to recognize your system's hardware capabilities.

1. Open your main GTA 4 game directory (where GTAIV.exe is located).

2. Right-click an empty space, select New, and click Text Document.

3. Name this file exactly commandline.txt (ensure it does not end in .txt.txt).

4. Open the file in Notepad and paste the following exact script from the very first line:

-nomemrestrict

-norestrictions

-noprecache

-availablevidmem 2048

-viewdistance 10

-detaildistance 10

-vehicledensity 15

-shadowquality 0

-texturequality 1

-nofog

-nosunshafts

-noextendedsunlight

-noambientocclusion

-fullscreen

-lockMouse

1. Click File -> Save and close the document.

### Step 2: Swap to the Correct Legacy DXVK Version

While FusionFix bundles a translation layer called DXVK to convert the game's old DirectX 9 engine into the efficient Vulkan API, the default modern version requires Vulkan 1.3. Older Intel/AMD graphics chips do not fully support this, causing game performance to drop to single digits.

1. Go to the official GitHub releases for DXVK and download DXVK version 1.10.3 (which relies on the highly compatible Vulkan 1.2 architecture).

2. Extract the archive, open the x32 folder (GTA 4 is a 32-bit application), and copy the d3d9.dll file.

3. Paste this file into your main GTA 4 folder, replacing the one previously placed there by FusionFix.

### Step 3: Strip Away Heavy FusionFix Enhancements

FusionFix adds several modern graphical features that destroy integrated laptop GPUs. Launch the game, head into your pause menu, go to Options -> Graphics, and forcefully disable these specific render-heavy settings:

* Windowed Mode: Set to OFF (Crucial to make the game stretch to full screen and lock your mouse cursor).

* Volumetric Fog: Set to OFF.

* Sun Shafts: Set to OFF.

* Extended Sunlight Reach: Set to OFF.

* Ambient Occlusion: Set to OFF.

* Tone Mapping: Set to OFF.

* Anti-Aliasing: Set to OFF.

* Shadow Filter: Set to Sharp or Softest, and toggle Console Shadows to ON.

### Step 4: Drop Your Native Resolution (The 4:3 Aspect Ratio Trick)

Integrated graphics hardware hits a physical processing wall trying to render high-definition 1080p pixels.

* Lower your in-game video resolution to 1024x768 and adjust the Aspect Ratio option to 4:3.

While the game will look slightly boxy and retro, cutting down the overall pixel rendering grid frees up immediate processing resources, giving your laptop graphics chip a massive frame rate boost.

### Step 5: Cap Performance at 30 FPS for Stability

GTA 4's physics and driving engines are mathematically optimized around classic console baselines. Instead of letting your laptop wildly fluctuate between 20 and 45 FPS, use the FusionFix FPS Limit slider to lock your game strictly at 30 FPS, with VSync enabled. This completely eliminates micro-stutters, minimizes input lag, and keeps your laptop from overheating.

### The Golden Rule: Always Stay Plugged In

Windows power profiles will immediately throttle your processor and graphics speeds the moment your laptop runs on battery power. Always keep your charger plugged into the wall while playing to ensure your system gives the game maximum priority over your hardware!

Having seen a lot of vids about GTA VI makes me think some people are confusing two things about GTA VI:

GTA V was mainly about L.A. / Los Santos. Plus a bit more.

GTA VI is about Leonida / Florida. Not just Vice City / Miami.

That means maybe we get: Miami, Tampa, Ft. Lauderdale, Orlando, Everglades.... And THAT would be awesome, wouldn't it?

It'd be HUGE... It's going to be huge.

Michael's is about 20 to 30 million in Beverly hills just by the location itself wheras franklin 10 to 20 million in Hollywood Hills.

Edit whose house do you think would cost more

Is it better to have 2x25 Tier 1 or 1x50 Tier 1?
