The problem of cursor flashing exist with nglide but the problem of framerate and sound with cursor moving doesn't exist with nglide.

Try 2.78.2 version and latest version of DOSBox ECE

Last version of dosbox ece doesn't allow to use glide wrapper as dgvoodoo or nglide.

The changelog of 2.78.2 doesn't modify anything about glide related things.

Is there any trick when running this game in DosBox?
My installation (old one) crashes right at startup. It's maybe because it's not configured but when I set up the sound configuration with the game config tool then it says that cannot write the config file.

I use no trick to run this game in dosbox.
I use dosboxece + dgovoodoo2 files.

If you look into it, remember this:
Re: Glide bug in Lands of Lore 2
Though since the game is broken in both dgVoodoo and nGlide it might just be something with how DOSBox Glide passthrough patches work.

I don't have teleportation effect.

Are you saying the effect doesn't display, doesn't take ages, or that it works properly? Have you tried the savegame linked? Could be different kinds of teleporters in the game.

Thanks, I forgot about that topic. That means LOL2 ran for me at that time in DosBox. 😁
I'll try out another installation.

It works properly except the problem sthat I ihave indicated in the first message.

How?

I'm using DOSBox ECE 4466 + dgVoodoo 2.78.2 and teleporters are broken. I can't see any way to get them working, so again are you sure you tested with the linked save? And going through the teleporter worked smoothly? If so, can you describe your entire install and configuration process?

With major issues like that, doesn't seem to be much point in fixing the cursor flickering.

If you select voodoo graphics and 1024kb in memory size in dgvoodoo 2 options, there is no teleporter bug. The teleporter bug arrive with 2048kb memory (same problem with 4096 kb). I don't know why but maybe, dege can explain why.
With nglide, there is this bug but I don't know how modify memory size in nglide.

Solve the cursor flickering is important.

That's great that that's a simple fix. I did some testing because I thought I had the cursor working nicely with dgVoodoo earlier, but I can't reproduce it. Guess the setup I got it working OK with was nGlide, which doesn't have as much problems with the cursor as dgVoodoo (though it just crashes with teleporters), so I doubt it's entirely a SDL issue as mentioned earlier.

I really want to play this game in 32-bit color. High resolution would be nice too, but I can't handle the dithering most Glide emulation setups give for this. The Windows version is crap because of aspect ratio issues and rendering bugs.

So yeah, hopefully Dege finds something out.

Finally I could check this out (altough I used my old DosBox Ykhwong build). The cursor flashing occurs because the game kinda 'emulates' the hardware cursor and draws it directly into the front (visible) buffer.
Even with built-in Glide emulation I get some flashing.

For the framerate problem, an option 'Batched update for front buffer' like the one for DX could help but it wouldn't solve the flickering.
The flickering is non-deterministic anyway, it is minimal for me with the D3D11 backend and strongly comes with D3D12 (because of the underlying frame presentation model).

Thanks for taking another go at this issue! Trying the D3D 11 backend certainly does make a significant improvement to the mouse flickering over D3D 12. Much more playable.

On a side note, the way the cursor flickering gets worse for me as it gets higher in postion on the screen reminds me of Might and Magic Xeen, where you have to dial in the CPU cycles to avoid flickering or the cursor completely disappearing once it hits the top of the screen.

The 1024kb memory size setting certainly fixes the teleporter effect for me. Nice find!

EDIT: For my own system, using the GOG included DOSBox build with glide enabled still gives better performance (no video stuttering) than ECE does.

EDIT:Also, for some reason the mouse flickering gets much worse if I do NOT do any resolution upscaling with dgVoodoo, even with the D3D 11 backend. Weird.

With d3d11, I have flickering in fullscreen but not in windowed mode. With d3d12, I have flickering , in windowed and fullscreen mode

Dege, had you the time for this problem ?

No, unfortunately I didn't had.
