# Resolutions impact on frame rate?

Is there a certain ratio in performance difference between resolutions?
-(Example 1080P:4K=4FPS:1FPS)
The example given may not be right but used to help understand. there may not be a set ratio as it could be dependent on the game, but i figured if there was a consistent increase of pixels it would be a consistent need for more to be rendered?
ANY IDEAS???????

It's fairly linear, the more pixels rendered to bigger the performance hit.

If 1080p is 1 FPS, then 4k is 0.25 FPS.

1920 * 1080 = 2073600
3840 * 2160 = 8294400

8294400 / 2073600 = 4

There are a few ways you can do it, but in the case of 1080 and 4k it's exactly 4 times as many pixels, so take the FPS and divide by 4.

All the best!

But it's usually a bit more of a hit than half because at some point the bottleneck in the gpu can change places as it try to render that many more pixels. Might even hit a vram issue. Also like a 1080 will usually not lose but a couple of fps going from 1080 to 1440 as it will put a pretty hefty bottleneck on the cpu at 1080 (and still in some cases at 1440)

Ok so the frame rate is lower as more pixels are needed to be loaded in each frame. so by finding the total pixels used and dividing by another resolutions total pixels you could find the relative performance for that resolution? Correct me if I'm wrong I'm no tech expert

It's not always that simple buy it's a decent rule of thumb GPUs are just making pixels per second. The more they are required to make the less frames in a second are created. There are other factors. It this will usually get you close assuming you don't run out of vram
