In C: Program Files Rockstar Games Grand Theft Auto IV directory (this is the default install) create a text file called 'commandline.txt' (no quotes of course) edit it and add the command '-windowed' (no quotes) save the text file commandline.txt launch the GTA4 game and presto it is forced to use window mode. And since youre already add it. Commandline.txt - file with additional game settings. In the archive there are 2 options for the settings, for medium and weak PCs. The option for medium-sized PCs is also great for high-end PCs. In these files, only the teams personally verified by me, all other commands that cause problems in the game process, I ruled out. Then open the one you created or the existing one, commandline.txt paste this into the Text Document:-width 640 -height 480 -refreshrate? 75 -novblank -texturequality 1 -renderquality 0 -viewdistance 0 -detailquality 0 -shadowdensity 0 -nomemrestrict -availablevidmem 4.0 -norestrictions -percentvidmem 100 -noprecache -safemode -fullscreen -framelimit 100 -Noswapdelay -Managed -Usedirectinput.

Before performing the below, if you have read other (similar) guides that havent worked, please undo your changes – especially any compatibility modes for older versions of windows.
- Ensure the game is closed.
- Enter your steam library and right click GTA 4.
- Select properties and select local files and browse local files.
- Open the GTAIV folder (this should contain GTAIV.exe) – if you do not have a steam install, this may be slightly different.
Create a new .txt file (right click > new > text file) and rename to “commandline.txt”
Open the commandline.txt file and paste:“-availablevidmem 2048
-norestrictions
-nomemrestrict”
Ensure no quotations or spaces are present.
In your steam library, open the properties panel again > general. set launch options.
You must paste the same, but ensure there is a single space between each line, see below.
If you do not have GTA 4 on steam, you must right click the shortcut you use to open the game, select properties and under shortcut add ” -availablevidmem 2048 -norestrictions -nomemrestrict” into the target box, do not delete any text here. (This effectively does the same as above)
Finally, to ensure GTA 4 is using your GPU go into windows settings, not control panel.search graphics settings and select Desktop App and browse to find the folder we added commandline.txt. Here you should add the GTAIV.exe and the launcher exe (I had best results when adding both). You may also need to do the same in you GPU control panel.
For the control panel, ensure as many settings are set to application-controlled as possible. Enable threaded optimisation if you still have issues with GTA IV.
That’s it, start playing. GTA IV is a notorious port, so reduce graphics settings and slowly increase. Here are mine for a GTX 950 gpu:
