| Hey everyone,
I've been running Space Engine at around 8K resolutions when taking screenshots, but what I'm noticing is that the bloom doesn't seem to scale correctly as you go beyond 1080p. By the time you reach 8K or even 4K, the effect has diminished to the point where it's barely there at all. This is fairly common for games, but I was just wondering if it's supposed to be happening here or if there's a fix.
Furthermore, effects like the diffraction spikes disappear when you go beyond a certain res. Again, I'm unsure if this is just me experiencing this. The problem seems to affect all the recent builds I've tried.
Regular resolution:
8K:
Thx!

I don't think it is "supposed to be happening", it just does happen.

I mentioned this to SpaceEngineer a while back. What the engine really needs is proper scaling for these effects.
The only solution is to turn those effects up to be larger so when you do take high resolution screens they get scaled down to what they should be. Doing this can be quite tricky however.

| Cheers for the reply. I've updated the OP with screens, but it seems you know what I'm on about.
EDIT: What's kind of annoying is that the effect does actually draw correctly for a second or two after the window's resized, but vanishes when the programme becomes responsive again.

| That's probably just the old 1080 frame still in the buffer, stretched to fill the new resolution.

| Some more examples of how bad this can be after just moderate downsampling:
750x1000px:
1620x2160px:

| Yeah I've experienced this as well, and from what I've seen, the sizes are absolute values (pixels) instead of relative values (% of sceen height/witdh). That means your bloom and diffraction spikes gets 4 times smaller from 1080p to 4K, and same goes for the bloom.

| Warp effects scale with resolution and can get really messed up looking if you push into very high resolutions. Hopefully someday when proper environmental mapping and high resolution screenshot exporting is added such things won't be a problem anymore.

| This is a very strange problem, I certainly do not have this issue while running space engine with AMD's VSR at 4K (I've taken dozens of screen shots to use as backgrounds and have compared the quality between normal resolutions and 4K, no difference besides quality of course I could link some as proof if needed)
Perhaps VSR works differently than what ever method you use? or maybe 4k doesn't have as noticeable issues compared to 8k? (although I swear there is no difference what so ever on my end)
