Only with help, unless you play esports or lighter games. The GeForce RTX 5090 is the fastest gaming GPU NVIDIA sells. At native 4K it averaged about 111 fps across Tom's Hardware's raster suite and about 64 fps with ray tracing. In path-traced games such as Cyberpunk 2077 it renders roughly 28–30 fps at native 4K. Reaching 240 frames per second there takes DLSS upscaling plus multi frame generation at 4x to 6x, which multiplies displayed frames, not rendered ones. Responsiveness follows the rendered frame rate, so a "240 fps" image built from a 60 fps base still feels like 60 fps. In esports titles the 5090 can approach 240 natively, but there the CPU usually sets the limit.
How fast is the RTX 5090 at native 4K?
| Game or suite | Native 4K | With DLSS upscaling | With upscaling + multi frame generation |
|---|---|---|---|
| Tom's Hardware raster suite (11-game geomean) | 110.8 fps average | — | — |
| Tom's Hardware ray-tracing suite | 64.1 fps average | — | — |
| Cyberpunk 2077, path tracing (Tom's, DLAA) | 27.6–28.6 fps | 67 fps, DLSS Quality (The FPS Review) | 110 fps (DLAA + 4x); about 200 fps (DLSS Quality + 4x) |
| Alan Wake 2 (The FPS Review) | 87 fps, highest settings, no RT | 86 fps, high RT with DLSS Quality | — |
| Black Myth: Wukong, full RT (NVIDIA figures) | 29 fps | About 60 fps, DLSS Performance | About 240 fps with 4x (vendor claim) |
| Indiana Jones and the Great Circle (DSOGaming) | 41 fps average | About 60 fps, DLSS Quality | Over 160 fps with 4x |
Source: Tom's Hardware GPU hierarchy (updated 24 Jun 2026; Ryzen 7 9800X3D, native, high/ultra settings) and 5090 review (23 Jan 2025); The FPS Review (17 Aug 2026, Gigabyte 5090 Gaming OC); TweakTown reporting NVIDIA's own Wukong figures; DSOGaming (2025, ray-tracing level unclear). Displayed frame rates with frame generation are not comparable with native ones.
Against the RTX 4090, Tom's 2026 data puts the 5090 about 24% ahead at native 4K raster. Launch-era reviews found 25–35%, about 30% on average. Against the RTX 5080 the 5090 leads by about 43% in raster and 52% in ray tracing at 4K. More in RTX 5090 vs RTX 4090 and where the money stops making sense.
What do DLSS upscaling and frame generation add?
NVIDIA's DLSS stack on RTX 50 cards has three layers:
- Super Resolution renders at a lower resolution and upscales. The DLSS 4.5 second-generation transformer model arrived in January 2026.
- Multi frame generation inserts up to three AI frames per rendered frame (DLSS 4, 2025). Since March 2026, DLSS 4.5 can insert up to five (6x), with a Dynamic mode that targets your monitor's refresh rate.
- DLSS 5 adds neural lighting and launched in NBA 2K27 in September 2026. It is a quality feature with a cost: GameGPU measured the 5090 falling from 162 fps to 68 fps at native 4K with it on.
Multi frame generation is the only way the 5090 reaches 240 fps in path-traced games. In Tom's March 2026 test, even an RTX 5080 went from 60 fps to 247.7 fps in Cyberpunk at 4K with DLSS Performance and 6x. So the 5090's real advantage at 4K 240 Hz is not hitting the number. It is hitting it from a higher base frame rate, which keeps latency lower and artefacts less visible.
Frame generation fills a 240 Hz screen; it doesn't make a 60 fps game respond like a 240 fps one. Judge a 4K 240 Hz setup by its base frame rate.
Does 240 fps with frame generation feel like 240 fps?
Not quite, according to independent testing:
- Latency rises: Tom's Hardware measured PC latency rising from 35 ms with frame generation off to about 53 ms at 4x and 6x in Cyberpunk on an RTX 5070. At launch, 4x added about 21 ms on a 5090 at native 4K path tracing.
- Base frame rate matters: Hardware Unboxed recommends a base of at least 70–80 fps, ideally 100–120 fps, and around 120 fps for fast mouse-driven shooters. It also says 4x is best on a 240 Hz or faster monitor.
- Artefacts: reviewers report ghosting on fine edges and smearing on in-game screens at 5x and 6x. Tom's verdict was that multi frame generation "is not a performance cure."
The practical recipe on a 5090 is to use DLSS Quality or Balanced upscaling to get a base of roughly 80–120 fps, then let 2x to 3x frame generation fill the rest of a 240 Hz panel. In competitive shooters, turn frame generation off and lower settings instead. NVIDIA's Reflex 2 Frame Warp, announced to cut latency further, had still not shipped as of July 2026.
What does the monitor connection need?
A 4K 240 Hz 10-bit signal carries about 59.7 Gbps of active pixel data before blanking (3840 × 2160 × 240 × 30 bits, our arithmetic). That is more than HDMI 2.1 (about 42.6 Gbps effective) or DisplayPort UHBR13.5 (about 52.2 Gbps). Only DisplayPort 2.1 at UHBR20 (about 77.4 Gbps) carries it uncompressed. The RTX 50 series supports UHBR20, and it needs a DP80-certified cable.
Everything else uses Display Stream Compression (DSC). DSC is visually lossless, and TFTCentral notes that UHBR20's main benefit is avoiding occasional DSC-related quirks. A DisplayPort 1.4 monitor with DSC is not a bad 4K 240 Hz monitor. Our posts on whether 240 Hz is overkill and whether you can see the difference cover the display side.
Which games really reach 240 Hz at 4K?
- Esports and lighter titles (CS2, Valorant, Fortnite at competitive settings) can run at very high native frame rates. Here the CPU is the usual limit: with a 5090, a Ryzen 7 9800X3D beat a Ryzen 5 7600X by 37% at 1080p Medium. We found no reliable native 4K figures for CS2 or Valorant on a 5090, so we won't quote any.
- Raster AAA games averaged about 111 fps natively in Tom's suite, so upscaling plus 2x frame generation gets most of them there.
- Path-traced showcases start below 30 fps natively and need the full DLSS stack.
To get the most from the card, pair it with a fast gaming CPU and a PCIe 5.0 or 4.0 x16 slot. A 4.0 slot costs only about 1% in games. See why your RTX 5090 might never reach its full potential and PCIe 5.0 vs 4.0.

Frequently asked questions
Can the RTX 5090 run games at native 4K 240 fps? Only lighter and esports titles, where the CPU often becomes the limit. Demanding games average around 110 fps natively in raster and much less with ray or path tracing.
Is multi frame generation good for 4K 240 Hz? It fills a high-refresh screen smoothly, but responsiveness follows the rendered frame rate. Reviewers suggest a base of at least 70–80 fps before turning it on.
Do I need DisplayPort 2.1 UHBR20 for 4K 240 Hz? Only to run it without compression. DisplayPort 1.4 and HDMI 2.1 monitors use DSC, which is visually lossless, so they still deliver 4K 240 Hz.
Can an RTX 5080 do 4K 240 Hz? With DLSS upscaling and 6x frame generation, Tom's Hardware measured an RTX 5080 at 247.7 fps in path-traced Cyberpunk at 4K. That was from a 60 fps base, so it feels slower than a 5090 reaching the same number.
Which CPU should I pair with an RTX 5090 for high refresh rates? A fast gaming CPU matters most at lower resolutions and in esports. With a 5090, a Ryzen 7 9800X3D was 37% faster than a Ryzen 5 7600X at 1080p Medium, and 8% faster at 4K Ultra.
