Here’s a breakdown of potential solutions based on your description:
This document discusses optimizing NVIDIA GPU usage on laptops like the XPS series. It explains how hybrid graphic systems, utilizing both an Intel integrated GPU (iGPU) and an NVIDIA dedicated GPU, function. The iGPU always drives the laptop’s screen, while the Nvidia GPU acts as a co-processor for rendering frames in games. These rendered frames are then sent to the iGPU for display.
The primary focus is on configuring the settings within Intel graphics control panel to ensure the Nvidia GPU is utilized for gaming on external displays. It suggests checking various settings such as power management and Nvidia control panel settings to prioritize the Nvidia GPU over the iGPU, thereby maximizing performance when using an external monitor.
Not sure where the setting is but it's clearly still trying to use the igp on the cpu not your graphics card when gaming on the built in monitor. Not sure if it's in the Nvidia control panel or the power management settings of the laptop to change it over to the gpu
Here’s a rewritten version of the text, aiming for clarity and flow:
The issue of slow performance in games on an XPS 15 (specifically the 9560 model) often stems from how the integrated graphics are managed. The system is configured to use the Intel GPU to drive the primary display, while relying on the Nvidia GPU as a secondary processor for rendering frames. However, this setup can lead to performance bottlenecks if not properly optimized.
To resolve this, several steps should be taken. First, check the Intel Graphics Control Panel (accessible via the Start menu) and disable all power saving settings. Specifically, look for options related to display refresh rate on battery and ensure they are turned off. Experiment with re-enabling these settings one at a time to identify the problematic setting.
Another potential cause is the C8 power save C-State feature in the BIOS. Disabling this feature in the BIOS can sometimes resolve the issue, although it may impact battery life.
It's important to note that some XPS models are designed to utilize the Nvidia GPU for the external display port, while others like the XPS 9560 primarily rely on the Intel integrated graphics even for the main screen.
