[feature-request] Scale Mode: performance should improve

Scale mode performance is not smooth.

Playing Diablo 1 in scaled mode (DirectDraw) is very "jumpy" -- window stops rendering for 0.1 second, then jumps several frames. Both mouse movement and hero movement experience such issues. Basically now the game is runnable, but unplayable.

If I switch to Normal Windowed Mode or Full-Screen Mode, Diablo plays smoothly.

What can be done about those performance "spikes" ?

Even in normal windowed mode, it seems that the game is unplayable here because of mouse-movement inconsistencies. I am not sure it is even "smooth" here under any mode -- much less using the "scaled mode," though, as the original poster puts it.

Using v4.1 Beta1 gets rid of the mouse-movement inconsistencies referenced above.

In normal windowed mode, it seems smooth, too.

The problem thus resides where the OP has stated: upon the using of the "scaled" mode.

Another thing that works (have not tested, but SHOULD be working):

  • multiplayer Diablo (even though the FAQ states that VirtualBox is not supporting IPX):

simply extract the three dlls of the package to the Diablo folder, and select IPX inside the game to play under the TCP/IP protocol.

Sorry this is not a forum thread about that but nevertheless shows almost everything now works for the game Diablo (except and this one).

  1. Multiplayer Diablo works. I played in normal view mode. (not related to Scaled Mode performance)
  1. IPX works in guest level network, and hosts sees this as Ethernet.
  1. IPX discussion is way off-topic from this thread.

IPX discussion moved there, in case of potential interest:

Replying to twipley:

Using v4.1 Beta1 gets rid of the mouse-movement inconsistencies referenced above.

Sorry. I am trying Beta2 right now, on a new virtual machine because I wanted to test it through the command line, e.g.,

vboxmanage createvm --name "entertainment" --register && vboxmanage modifyvm "entertainment" --ostype windowsxp --memory 512 --vram 128 --accelerate3d on --audio pulse --audiocontroller ac97 --nic1 generic --nicgenericdrv1 udptunnel --nicproperty1 dest= --nicproperty1 sport=52011 --nicproperty1 dport=52011 --cableconnected1 on --usb on

and upon clicking on an inventory item, or on a spell on the list, the mouse gets moved to strange locations, where it should not be going. I did not suffer from this issue the last time I have tried (with v4.1 Beta2), and cannot seem to point my finger on the setting that is wrong here this time. It seems all my settings are the same than before, but the bug has reappeared upon trying on this new virtual machine.

Sorry if I am not _that_ much on topic. It is just that the game currently is not playable here, even on "normal" fullscreen mode.

twipley: Off-topic post. Go to forum.

Alright, I should have gone to the forums. (btw, fixed by disabling mouse integration host+i)
