Processor details: 11th Gen Intel Core i5-1135G7 running at 2.40GHz with 8 CPUs and about 8192MB RAM paired with an Intel Iris Xe graphics card plus a NVIDIA GeForce MX330. Since your GPU has only 2GB of VRAM, the system restricts resource usage to 512MB.
Verify the system details, it appears the iGPU is being used instead of the MX330.
It might be relying on the igpu library. Turn off igpu in the device manager or BIOS if you can.
In the task manager, while playing GTA IV, you notice activity displayed in the 3D area of the NVIDIA GPU.
