Experiencing major screen tearing in Portal?
You're experiencing screen tearing while using Portal on your older Asus ROG laptop with a GTX 965m. This issue might be related to the hardware limitations of the graphics card or the display itself. A G-sync monitor could potentially help stabilize the output, but moving back to your desktop with a more modern GPU would likely provide a smoother experience. Since you've encountered tearing before, it's possible the screen is nearing the end of its lifespan. Consider checking for firmware updates or contacting the manufacturer for further assistance.
Use VSync to match your frame rate with your monitor's refresh rate. The portal runs smoothly, usually between 200 and 400 frames per second. When the display doesn't sync perfectly with the screen's refresh, it causes visual tearing because the GPU sends frames that are incomplete. By limiting your FPS to match the monitor's refresh (or a multiple), you ensure a full image is shown each time, eliminating the tearing. The problem usually stems from excessive power usage rather than insufficient power. Activating VSync or using an external tool to cap your frame rate will resolve the issue.
