Bug Description

Got some problems with scaling in general. If I go above computer screen resolution (mine is 1080p or 3x res) game looks worse like if it got deep fried slightly. Also some games just get jaggies again at higher res. Here is some photos below.

Halo CE: 10x

Burnout 3 takedown:

Original Xbox Dashboard:

10x

1x (compared 1x because 10x felt like it looked 1x on the edges)

Expected Behavior

Having higher than native resolution should be like a anti-aliasing effect like in other emulators without some pixels fighting to be the one on screen.

xemu Version

0.6.2-10-gaa7acc8f64

Tried first version of introduction to resolution scaling and tried a few after the release and had same results

Additional Context

I have tried hard-scale branch and has not changed either.

Ok, so after doing some test (and reporting it on Discord) here a resume of the situation:

1. Halo does have what it look like to be a texture bleeding issue when rendered at any resolutions higher than native (starting right at x2), it doesn't matter if it is set on Fullscreen, Windowed, Center, Scale or any other combination, it can be easily seen on the menus, but it also affect the in game rendering, so if weird texturing appear, it may also be the culprit.

^ Open in large to see the issue ^ Comparison with x1 ^ Texture issues on the river with x10, not present in x1

2. Windowed mode does not apply all settings and graphical effect (either set on the driver control panel of the GPU or of the game/emu), unfortunately, the fullscreen version cannot be screenshoted properly (even with MSI afterburner), but here some example of jagged edge present in Windowed that are not in Fullscreen. ^ x4 with "Center" in Windowed, those jagged edges does not appear on Fullscreen

3. Having a too "high resolution" on lower resolution devices (either screen resolution or pixel density) will create the effect seen on the previous gif, a screen too sharp and too "full", instead, what some people want to achieved is a "downsampling" effect, aka, putting higher resolution to enhance the game graphics, which, for this to work, will require some settings and effects applied by the emulator on the final frame. ^ x10 a 4K screen (3840x2160)

^ As a comparison x10 on 1024x768 screen, with a lot of jaggies (pixel density too high)

I can confirm this effect is caused by no downsampling by changing scaling type on Xemu to center and increasing resolution which makes it zoom because it's trying it displays true resolution and doesn't have this graphical issue/display issue.

@Spidy123222 Could you add a link so it appears on the website

What was the hardware specs. I'm starting to find it might be only amd system related as I see friends with nvidia gpu's not have this issue at all and it look crisp.

I have nvidia gpu 2080 super & experience this issue.

Has anyone found a workaround or solved this issue?
