Find tips to boost Fallout 4 performance.
You're experiencing lower frame rates on your 4K TV when using Steam Big Picture and playing Fallout 4. At 1080p you see solid performance, around 20 frames per second, while 2K runs at about 62fps. It seems the higher resolution isn't translating to better performance on your TV. You're using the built-in upscaler, but the resolution settings in Steam aren't matching what your TV expects. Consider adjusting the resolution in Steam settings to match your TV's native resolution, or try using a different upscaler if available. The 30fps at 2K and 120fps at 1080p suggest the issue is related to resolution scaling rather than frame rate.
