[Nintendo Switch] Dynamic Lighting Slowdown

[loafofdread]

Whenever any kind of dynamic lighting is active (flashlight, environmental lights, etc) it causes severe fps loss. The only solution is to disable it entirely, but renders the game unplayable.

Try to set cvars gl_vbo 1 and gl_vbo_dlightmode 1 into opengl.cfg.
Anyway it's an old trouble with glBegin/glEnd-chains and immediate GPU mode.

VBO can be enabled from the menu, btw @nekonomicon

As for gl_vbo_dlightmode, it can be toggled from the console or in config. But it requires map restart.

Oh, nice.

Unfortunately, this does not fix the issue. I should add that I am using the latest release as well.

It is trouble with cpu write while rendering. Disabling VBO might help a little (because it does not mix lightmap update with rendering so often), but generally only way to fix this is uploading lightmap blocks with render/blit calls or even completely move lm building to gpu. TexSubImage cpu-locks texture buffer instead of just creating transfer command on most implementations

How severe is severe? In my testing it was there, but it was not severe at all in most cases.

If any kind of dynamic lighting is present in a busy area it can drop below 10fps. It's especially bad in Opposing Force.

It wasn't that horrible back when I tested it. Something must've changed then.
UPD: Just checked on my Switch. With either the old build I had on there or the latest version I can have the flashlight on, run around shooting guns, etc, and it does not drop below 60. I'll upload my config in a bit.
What firmware version do you have?

[fgsfdsfgs]

Here are my configs. You can try them, just keep in mind that the keybinds are not set properly. Of note is that gl_vbo is 0.

I am running the continuous master build on an Erista Switch with FW 19.0.0 and AMS 1.8.0.

Trying your configs seems to have helped a bit, but it still really slows down in areas where there are environmental dynamic lights, especially if using the flashlight.

For an example of a bad area like this, try my save from Opposing Force.
