Intel HD 4000 and Nvidia GEFORCE GT 630M 2GB, Detects only Intel HD

[Veleck]

I have the Nvidia GT 630 (2gb VRAM) and I've put GTA 4in the Nvidia Host list so that it opens with Nvidia but ingame It still uses Intel HD 4000 Graphic card that annoys me ! I almost tried everything to make it work. I created an commandlist file in the installation folder. changed launch options to launch whitout restriction but nothing worked :s. Can someone please help me?

find a ways to disable your integrated video card. also it would help making sure that your system is updated i.e. bios, video drivers etc,

How do oyu know that the game is still using your other video card? Run a benchmark in GTA 4 and open the save file, at the bottom of the report you can see which card the game used.

good luck.

Please bare in mind that, GTA 4 is very badly optimized for PC, I have a decent gaming laptop and it struggles to run it smoothly, looking forward to any updates in the game, drivers, and bios to see if it work better over time or at least when GTA 5 PC comes out if ever..

Simply open your Nvidia Control panel, then open 3D settings, in the "Preferred graphics processor" set "High-performance NVIDIA processor".
Done, now you will run all the programs through your Nvidia card, if you use benchmark in GTA IV, it will still say your card is Intel, but it's just a bug or something..you will run it on GT630m
If you don't trust, just set "Integrated Graphics" instead of "Nvidia" and run the game, your FPS will go down really nice..
