General Performance Problems (Problem Fastmem?)

[ToniBC]

I have done several tests and I cannot find a solution that relates to the core options, that is why I put it here as a general problem. All tested under Windows 10 with the latest Nightly.

Dolphin core in Libretro has somewhat erratic or inconsistent performance. That is, if we compare it with the Standalone version, for example, in the game Resident Evil 3, it works at a frame rate of 25 or 30 with the patch, but in Libretro it stays at values ​​of 22-25 or 28- 30 fps. Not that it's a big deal, but you can tell that something is wrong.

Another game is for example Super Mario Sunshine, if we move when leaving the plane, we see how the frame rate drops to 28 in certain places, something that does not happen in the standalone version.

I am not referring to the jumps or lows by the cache generation, it is something permanent. It is as if the synchronization was not done correctly, since, if you accelerate the game, in Resident Evil 3 for example, the game exceeds 50 or 60 fps, so it is not a performance problem.

I have tried to deactivate the Fastmem option and there the game remains more consistent, but it generates sound problems such as clicks and the like.

Not that it is something super record, but in Libretro something does not work well in this core.

Thanks.
