Beach Spikers USA-EU texture problem.

[stizzo]

Goodmorning everyone.

The game for gamecube Beach Spikers of SEGA, has problems of visualization, in the correct rendering of the textures:



In the menus everything is fine, in the game, when the time comes, I get the problem as in the picture.

If I move to the left of the field, with the pad, strangely the textures are recreated correctly, if I move to the right of the field, the textures deform.

Even in the initial movie, after a few seconds of viewing the scene, the screen appears black.

I tried with all the possible settings and changing between OGL and Vulkan, same effects.
Even in the last build of the emulator, have the same problem.

Nokia 8, Snapdragon 835, Android 8.1

PS: in the latest Dolphin builds, I notice a lot of stuttering and performance downgrades.

I have at this time, version 5.0-8713.

I noticed the stuttering problems with the last ten builds of the emulator.

The problems occur indifferently from the used differents bancked.

Thank you.

PPSS: I believe that 2D videos are not accelerated via hardware, but via software, It's right?

Sorry for en.

Does the same issue occur on the PC version? It might be a GLES or driver issue.

On the PC, I have not tested it.

I do not think it's a driver problem, but I think the texture problem is very similar to that of Metal Gear texture flickering.

Vulkan, do not use OGL-ES.

A little while ago, I tested the last build, the stuttering is still present.

the builds I use, are 8713-15. (there is a slight form of stuttering, but everything flows quickly, smoothly and without slowing down)

the benchmarking game is Bloody Roar Extreme. (japan version)

I have chosen this game specifically for the various tests, because it is frenetic and very fast in framing changes and transformations. (many video effects, including motion blur, lights, reflections, etc.)

This combination of polygons, framing changes, graphic effects and speed, stress a lot cpu and gpu.

The best terminals, from my point of view and to play with the Dolphin, at the moment are:

Google Pixel 2 XL

Nokia 8

Xiaomi Mi 6

All on Snapdragon 835 and with the most accurate and compatible drivers and that have less problems with the games.

With the last Build (8830), the stuttering has decreased, but it still takes some work.

Still texture problem?

[stizzo]

With Beach Spikers? Yes!

Update: to better understand the bug in Beach Spikers;





according to what is reported in the wiki and for desktops:

Quote:Problems
Seams
Small seams may be visible along the edges of some screen elements. Refer issue 6833.

Blinking (Vulkan/DirectX)
Odd blinking of some visual elements may occur. Disable "Fast Depth Calculation" to resolve. Refer issue 10007.

I hope that some of the developers will read and create a fix/workaround.

The game is beautiful and deserves to also run on Android.

PS: With the latest build, 8838, stuttering, has returned to the acceptable levels of versions 8713-15.

Thank you so much to the willing programmers and developers.

PPSS: the screenshots are captured with the Dolphin setting and my Android 8.1
