One thing that sometimes gets overlooked is the chipset and storage drivers—Windows Update doesn’t always grab the latest, and on older hardware, having the newest Intel chipset drivers especially can help with those random stutters. Also, I’ve noticed that disabling Fast Startup in the power settings can sometimes smooth out weird lag spikes if you’re dual-booting or have swapped major system components. Game Mode is a mixed bag for me; it feels like it helps when there are a lot of background processes, but on a clean system, I barely notice a difference.
As for auto-HDR, I found it mostly just makes SDR games look weird unless you tweak your display settings—no real performance impact either way, in my experience. Variable refresh rate, on the other hand, is great if your monitor supports it but you have to enable it in both Windows and the monitor’s own settings for any effect. Anyone experiment with different power profiles? The “Ultimate Performance” mode sometimes unlocks a bit more headroom but tends to crank up power usage and heat.
Curious if anyone’s tried undervolting or manual fan curves to squeeze out more consistent FPS on older GPUs? That’s helped me more than any Windows update, honestly.
