Stutters during gameplay

[doggogit]

Brief description

On previous iterations of FPS+, these weird stutters during gameplay wouldn't happen, but as of the current 6.1.0 pre-release, these keep happening pretty frequently, no matter the song I'm playing.

This happens with both characters, music and graphics cached or nothing cached at all.

Are you able to provide a video of this happening? Because this doesn't seem to happen for me.

I'd love to, I had to sleep early last night so I forgot to reply to this, my bad

GitHub in its infinite wisdom doesn't like videos >10MB so I'll resort to Streamable

Footage with characters, graphics and music cached

Footage with nothing cached

I have RTSS (RivaTuner Statistics Server) enabled and you can see spikes mid-gameplay with the frametime graph

These still occur even when I'm not recording

(I do apologize for the weird cropping, I have no idea how to crop with OBS properly lol)

Interesting, I will look into it.

Do you think you could try removing updateScoreText() out of the PlayState update loop and see if that makes it run better.

That'd require recompiling, but sure!

Do you want me to completely remove the line or move it in another function?

Just comment it out and see if stops the stuttering, obviously it will break the the score text but I think the stuttering might be due to the fact that the text being updated every frame. I noticed a little bit of stuttering for me occasionally and I think this helped but I'm not really sure since the stuttering didn't happen consistently for me. If this at least part of the cause I have fix for it but I just need to confirm that I will actually help.

Just in time as I'm writing my reply LOL

Okay, so, update, while commenting out the updateScoreText() function out of the update loop does boost my FPS by fucking 200, I think I might've found the actual root cause of the stutters

I noticed that it happened again, but only once or twice, and that's because the NVIDIA GPU hits 1% usage and then finds it's footing a few milliseconds after and it jumps back up to regular usage again

Below is a screenshot I took from a clip while playing Fresh Erect on the compile build with the updateScoreText() func commented out:

Hopefully re-installing the NVIDIA GPU driver will remedy the issue

Interesting since for me commenting out the text doesn't really effect my frame rate but I'll definitely add that fix for better performance anyways since it seemed liked it helped.

Comparing footage from last night, without anything cached, the framerate was ~500, and without the score text, it was peaking at like 800 and something LMAO

Just pushed a fix, lemme know if it works better when you get the chance.

I'll try out tomorrow, hopefully that's no problem for you
