GlideN64 plugin: HLE or LLE?

[Atsix]

Hi everyone,
I'm using the latest GlideN64 build with Project64 2.3, and I would like to know if you guys think I should use HLE or LLE graphics? I realize that LLE is normally slower, but I tested it and LLE runs just fine for me most of the time.

I'm asking because I understand that LLE is more accurate than HLE and it could fix some issues that HLE can't, and I just wanted to know if there's any downside to using LLE graphics.

Thanks in advance.

PS: By the way, to use LLE graphics I just have to uncheck "Graphics HLE" on the plugin selection menu, right?

GLideN64's LLE isn't too useful. Might as well just use z64gl imo, if you want LLE.

I would like to see glide64's lle be as good as z64gl ... but need to get android faster first

The "downside" is that the HLE microcodes in most of what you'll run are documented and functionally direct.

In context, drawing a cylinder or sphere in LLE requires multiple triangle commands, but in HLE microcode if there is a command for drawing cylinders or spheres you can write C functions to not have to individually graph each triangle but try to process a vertex array. (Depending on your GPU's advancement over the RCP's this may or may not amount to much.)

Otherwise you might have to worry about the CPU or the RSP sending corrupt display lists, and usually only LLE is affected by this.

Otherwise not really a downside to using LLE graphics.

With the default plugins, yeah. For older versions like the 1.6 RSP emulation plugin that will have no effect, but it can't hurt.

I see. I'll stick to GlideN64 HLE then. Thanks!

All right, I'll give it a try. Do you know where I can get the latest version of z64gl?

Original author has been inactive for years, but someone else has forked it and improved the plugin. https://github.com/purplemarshmallow/z64

How much has changed?

Thanks! Just another question guys, which plugin do you think is better, Glide64 or GlideN64? Performance is not an issue for me because I can run both of them at full speed, so I wanted to know which one is more accurate and more compatible.

Some bug fixes + performance improvement in some games.

What would be nice is something equivalent to z64gl but rewritten for modern systems and using up to date research. Pity that will never happen.
