Fast Racing Neo Graphic Pack Resolution Issue #427

Open Peduls opened 4 years ago

Peduls commented 4 years ago

When changing the resolution via the graphic pack for Fast Racing Neo certain tracks (specifically tracks with lens flare) look like this. It doesn't happen every time but seems to be more likely after playing for long periods of time. Happens on Vulkan but haven't seen the issue while using OpenGL. Very similar issue as #426 screenshot_5

Those seem like the same graphical bugs I get with Vulkan, which aren't related to the graphic packs. You can make a post on Cemu's bug tracker if you want, although I doubt that the devs aren't aware already. Feel free to reopen this issue if you think this only occurs when you're using graphic packs, but usually these issues are just related to the still experimental Vulkan renderer.

It does only happen in Vulkan but it also only happens when increasing the resolution via the graphic pack. I talked about this issue on the Cemu discord and they said it's a graphic pack issue.

I am unable to reopen this issue as it was closed by a Collaborator.

This is an issue that happens when the graphics-pack changes the resolution. Changing anisotropic filtering, without changing the resolution, does not cause this issue. Without using the graphics-pack, this issue does not happen for me.

After changing the resolution-setting once, even setting it back to the default-setting will result in this issue. Disabling the graphics-pack and then enabling it again, after the settings of it were reset by restarting the emulator, will allow using it for anisotropic filtering, without this issue, again.

There are static patterns added to certain effects and some menus; these patterns change every time the game is started.

I usually see 3 different, static patterns in these parts of the game:

Sometimes the patterns are made of textures; for example: the letters of some font, or tree-textures.

The title-screen also always shows a line that should probably not be there. On the cup-selection-screen and the vehicle-selection-screen, some of the shapes in the background are not displayed.

Afaik it's a memory corruption issue. Having higher resolutions means that there's a more likely chance to get the issue since there's just more memory that's getting improperly written too. If you do a few races without the resolution pack you'll also see the framebuffer artifacts. I think a similar issue is seen in Hyrule Warriors, although in a much lesser sense and only in the menus.

I'll open the issue here, although graphic packs don't really have the ability to fix graphical artifacts like these regardless.

Thanks!

I did not notice such graphical artifacts when playing without graphics-packs, so i added to this issue, instead of opening one on the "Cemu"-repository.

I tested decreasing the resolution now (including the minimum that is selectable for both TV and GamePad); the graphical artifacts were basically the same.

Here is a video showing the issue when the resolution is changed (3840x2160 was chosen in Cemu for this video): FAST Racing NEO.webm

The video begins a few seconds after starting the game.

Such graphical artifacts always appear. The patterns remain identical when returning to the screens they are visible on, after going to another screen or beginning a race. When starting the game repeatedly, the patterns usually change each time.
