Calculating render resolution...
Choose an output resolution, upscaling technology, quality mode, and optional native FPS to calculate internal render resolution.
What the DLSS 4 / FSR 4 Quality Setting Calculator Shows
The DLSS 4 FSR 4 Quality Setting Calculator turns vague upscaling labels into concrete numbers. Instead of guessing what Quality, Balanced, Performance, or Ultra Performance means, you can see the internal render resolution, the percentage of native pixels being shaded, the approximate FPS uplift, and whether frame generation is likely to make sense for the selected GPU family.
Render resolution is deterministic. If a 4K output uses a 1.5x Quality scale, the game renders at 2560 x 1440 before the upscaler reconstructs the final 3840 x 2160 image. FPS is different. The calculator estimates performance from pixel workload and a conservative efficiency factor, but real FPS depends on the game engine, CPU limit, VRAM pressure, driver version, and scene complexity.
DLSS and FSR Quality Modes Explained
Upscaling modes are usually named by image-quality intent, not by the actual resolution. Quality keeps more source pixels and generally preserves detail better. Balanced lowers internal resolution further to gain more performance. Performance mode is useful when ray tracing, path tracing, or 4K output pushes the GPU hard. Ultra Performance is mainly appropriate for 8K or emergency FPS recovery because the internal render target becomes much smaller.
DLSS, FSR, and XeSS can share similar names while using slightly different scale factors in practice. DLSS Balanced is commonly modeled around a 1.72x per-dimension scale, while FSR Balanced is commonly modeled around 1.70x. That difference is small, but this tool keeps the tables separate so the render-resolution output stays honest.
What Resolution Does DLSS Quality Render at in 4K?
DLSS Quality at 4K renders at 2560 x 1440. That is 3.69 million internal pixels compared with 8.29 million native 4K pixels, or about 44.4% of the native pixel workload. This is why Quality mode can look close to native while still giving a meaningful performance uplift, especially in GPU-limited scenes.
FSR Quality uses the same 1.5x scale factor in this calculator, so its 4K internal resolution is also 2560 x 1440. The final visual result can still differ by game because each engine supplies motion vectors, depth, exposure, reactive masks, sharpening, and frame pacing differently.
Frame Generation vs Real Rendered FPS
Frame generation increases displayed frames by inserting generated frames between rendered frames. It can make motion look smoother, but it does not raise the game simulation rate in the same way as rendering more real frames. A system rendering 55 FPS and presenting generated frames can feel much better than one rendering 28 FPS and relying on generated frames to cover the gap.
That is why the calculator separates estimated rendered FPS from generated or perceived FPS. If latency matters, prioritize a higher rendered FPS base, enable vendor latency features where available, and avoid treating frame generation as a fix for a very low native frame rate.
Best Quality Setting by Resolution
At 1080p, Quality mode or native anti-aliasing usually makes the most sense because the internal render target gets small quickly. At 1440p, Quality is the safest first choice, with Balanced as a fallback for demanding games. At 4K, Quality, Balanced, and Performance are all practical depending on ray tracing load and refresh-rate target. At 8K, Ultra Performance becomes a realistic option because even one third of 8K is still a sizeable internal image.
| Mode | Scale | Render Scale | 1440p Internal | 4K Internal | Best Use |
|---|---|---|---|---|---|
| Native AA | 1.00x | 100.0% | 2560 x 1440 | 3840 x 2160 | Maximum clarity |
| Quality | 1.50x | 66.7% | 1706 x 960 | 2560 x 1440 | Best first choice |
| Balanced | 1.70x-1.72x | 58.0%-58.8% | about 1506 x 848 | about 2233 x 1256 | 4K FPS recovery |
| Performance | 2.00x | 50.0% | 1280 x 720 | 1920 x 1080 | 4K ray tracing |
| Ultra Performance | 3.00x | 33.3% | 854 x 480 | 1280 x 720 | 8K or last resort |
FAQ
What resolution is DLSS Quality at 4K?
DLSS Quality at 4K usually renders internally at 2560 x 1440 before upscaling to 3840 x 2160. That is about 44.4% of native 4K pixels.
Is DLSS Balanced better than FSR Quality?
They are different settings with different goals. FSR Quality uses a higher internal resolution than DLSS Balanced, while DLSS may have a stronger reconstruction model in supported games. Compare both in the specific game when possible.
Does frame generation increase real FPS?
Frame generation increases displayed frames, but it does not increase fully rendered game frames or input sampling in the same way. It works best when rendered FPS is already reasonably high.
Should I use Ultra Performance at 1440p?
Usually no. Ultra Performance at 1440p renders from a very small internal image, so detail loss and instability are easier to notice. Try Quality, Balanced, or Performance first.
What is the best DLSS or FSR mode for ray tracing?
Start with Quality. If heavy ray tracing or path tracing still misses your FPS target at 4K, move to Balanced or Performance. Use Ultra Performance mainly for 8K or extreme recovery.
