Resolution FPS Estimator
Switching from 1080p to 1440p or 4K costs performance. Enter the FPS you get now and see a rough estimate at another resolution, based on how many more pixels the graphics card has to draw.

How to use it
- Pick the resolution you play at now and enter your average FPS.
- Pick the resolution you are thinking of moving to.
- Read the estimate. It is a range, because real games scale differently.
How the estimate works
When your graphics card is the limit, the frame rate falls almost in step with the number of pixels: a 4K screen has four times the pixels of a 1080p screen, so a card that gives 160 FPS at 1080p may give around 40 to 60 FPS at 4K. The range shown covers the usual cases, because games that are limited by the processor lose less than games that are limited by the graphics card.
How to claw back performance
- Use an upscaler such as DLSS, FSR or XeSS to render at a lower internal resolution.
- Lower the settings that cost the most, such as shadows and ray tracing, before lowering textures.
- Check that you are really graphics-limited. If lowering the resolution does not raise FPS, the processor is the limit.
Frequently asked questions
How many FPS do I lose going from 1080p to 1440p?
The pixel count goes up by 78 percent, so expect roughly 20 to 40 percent fewer frames if the graphics card is the limit.
How much harder is 4K than 1080p?
Four times the pixels. Real performance drops by about half to three quarters, depending on the game.
Is the estimate exact?
No. It is a guide. Different games, settings and processors change the result, so test in your own game.
Does resolution affect the processor?
Very little. If your FPS does not change when you lower the resolution, the processor is probably the limit.
