A custom PC setup combining a GeForce RTX 4080 with a GeForce RTX 2070 Super successfully runs the Lossless Scaling software to double gaming frame rates. In this setup, a modern GeForce RTX 4080 acted as the primary graphics adapter to handle all graphics rendering. The secondary GeForce RTX 2070 Super GPU handled the Lossless Scaling Frame Generation (LSFG) processing.
Offloading the frame generation workload to the secondary graphics card prevents any drop in the primary card’s rendering performance. Operating both cards in tandem effectively distributes processing tasks without introducing noticeable input lag. The custom configuration successfully doubles frame rates in demanding modern gaming applications.

The user tested the dual-GPU configuration at a 1440p resolution across two popular video games. In *Cyberpunk 2077*, running with ray tracing set to Overdrive mode and DLAA antialiasing, the base frame rate of 70 fps increased to a stable 140 fps after enabling LSFG. In the competitive shooter *Fortnite* running at Epic graphics settings, the frame rate doubled from a base of 70 to 100 fps up to a final range of 140 to 200 fps.
This hardware division of labor acts as a modern replacement for outdated SLI configurations by allowing different GPU generations to work together. Because the secondary card only processes frame generation data, the desktop runs stably, quietly, and without generating excessive thermal load.
This setup requires a secondary PCIe slot on the motherboard to house the second GPU. Attentive PC builders should also ensure that their desktop chassis has sufficient space to clear both cards. For instance, the user had to upgrade from a compact Lian Li chassis to a larger Corsair Carbide Air 740 case to resolve space restrictions.
As graphics demands increase, local scaling software could become a popular alternative for budget-conscious gamers looking to reuse old hardware. Dedicated developer forums will likely see more dual-GPU benchmarks as enthusiasts continue to test diverse hardware configurations.
