At 1440p, a powerful GPU like the RTX 4090 often has headroom to spare, meaning the CPU becomes the limiting factor. Enabling DLSS upscaling in this scenario barely moves the needle because it reduces GPU workload that was already underutilized. DLSS Frame Generation can partially help since it works on the GPU side without lowering render resolution, but introduces input latency and artifacts that make it unsuitable for competitive multiplayer. The recommended alternative at 1440p with GPU headroom is DLAA, which enhances image quality rather than chasing frame rates. ## Full article daily.dev links to this article rather than hosting it.
