Description

Game Name?

Disney's Cars 2 -

What's the problem? Describe what went wrong.

Turning on logs results in even worse performance than usual with this game. The problem is this message being spammed:
13:16:946 TextureCacheBase.cpp:1669 E[Video]: Memory stride too small (0 < 1280)

What steps will reproduce the problem?

Use Dolphin to emulate game.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

It is present in the latest development builds.

Is the issue present in the latest stable version?

I'm not 100% sure on the version, but phire added some stride checks to prevent crashing a while back and that's where this message originated.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

I don't think bisecting will help, the message was designed to get cases investigated.

History

#1 Updated by degasus almost 2 years ago

This message is there on purpose. We don't know the behavior of overlapping lines. The copy logic might be clever and skip the former or the later part, but we have no clue which one. Maybe someone should write a hardware test.

#2 Updated by JMC4789 almost 2 years ago

We need a global issue for this since a bunch of games hit it.
