HP Omen 16 (i7-12700H, RTX 3070) running slow and underutilizing GPU — need help optimizing
Hey everyone, looking for some help diagnosing poor performance on my HP Omen 16.
Specs:
CPU: Intel i7-12700H
GPU: NVIDIA RTX 3070 (8GB)
RAM: 16GB DDR5 single channel (1 stick)
Storage: NVMe SSD
OS: Windows 11
The issue:
My system feels sluggish and the GPU is consistently underutilized during gaming. In Task Manager I'm seeing low GPU usage (15-20%) even in demanding games like Forza Horizon 5. CPU usage also seems inconsistent.
What I've already done:
Fresh Windows reinstall
Latest NVIDIA drivers installed
Hardware accelerated GPU scheduling enabled
High performance power plan set
RTX forced as primary GPU for all game executables
Disabled SysMain, GameDVR
Game Mode enabled
What I suspect:
I'm running single channel RAM (1x16GB DDR5) which I know creates a memory bandwidth bottleneck, especially starving the iGPU and potentially the dGPU too. But even accounting for that, the system feels slower than it should.
Questions:
How much real world FPS difference will going dual channel (2x16GB DDR5) make on this config?
Is there anything else I'm missing for Omen 16 optimization?
Anyone else had issues with Intel UHD eating GPU resources on this laptop?
