RTX 5090: Tools Matter

Modern GPU reviews are no longer one-number stories: on the GeForce RTX 5090, the result changes with upscaling, frame generation, path tracing, drivers, and even the logging tool. (nvidia.com) A game frame starts as an image the graphics card renders, and newer tools can rebuild parts of that image or invent extra in-between frames to raise the counter on screen. Nvidia said on January 6, 2025 that DLSS 4 added Multi Frame Generation on GeForce RTX 50-series cards, creating up to three additional frames per traditionally rendered frame. (nvidia.com) Nvidia also said DLSS 4 moved Super Resolution, Ray Reconstruction, and DLAA to transformer models, a newer artificial-intelligence design the company said improves detail in motion, temporal stability, and ghosting. In plain terms, that means two RTX 5090 charts can differ because one test is drawing more of the picture natively while another is leaning harder on AI cleanup. (nvidia.com) That has pushed reviewers to separate “rendered” performance from “displayed” performance. FrameView 1.8 now logs the Multi Frame Generation multiplier in the background, and Nvidia’s example says 100 frames per second at 2x Multi Frame Generation means 50 rendered frames and 50 generated frames. (nvidia.com) The measurement problem widened again on March 31, 2026, when Nvidia rolled out DLSS 4.5 Dynamic Multi Frame Generation and a 6x mode through the Nvidia app beta. Nvidia said Dynamic mode can shift multipliers in real time to match a display’s refresh rate, so a benchmark can change if the monitor, cap, or app settings change. (nvidia.com) The RTX 5090 itself arrived on January 30, 2025 with a Game Ready Driver tied to DLSS 4 features and new Nvidia app overrides. Nvidia said owners of the RTX 5090 and RTX 5080 needed that release driver, which is why reviewers now call out driver versions alongside game patches and graphics settings. (nvidia.com) Early RTX 5090 reviews tried to pin down “raw” speed by testing without upscaling or frame generation, then adding DLSS results separately. TechPowerUp’s January 23, 2025 review said its testing included performance “without upscaling or frame generation, too,” even as the card launched with 32 gigabytes of memory and DLSS 4 support. (techpowerup.com) That split reflects how path tracing works in 2025 and 2026 game tests. Full ray tracing or path tracing simulates more realistic light, shadows, and reflections, but it is so expensive that vendors pair it with reconstruction and frame generation to keep high-end cards playable at 4K. (nvidia.com) Nvidia’s own launch material for DLSS 4 said Cyberpunk 2077 on RTX 5090 could reach 4K 240 FPS with full ray tracing and that the gain came from the full DLSS stack, not from brute-force rendering alone. That is why current comparison tables increasingly list the DLSS mode, frame-generation status, and ray-tracing preset next to the frame-rate number. (nvidia.com) The upshot for readers is simple: an RTX 5090 benchmark now needs a settings label as much as a score. Without the driver version, DLSS mode, frame-generation multiplier, ray-tracing preset, and tool version, two “FPS” results may be measuring different things. (nvidia.com)
