Description

my system:

ArchLinux 3.2.1-1-ARCH #1 SMP PREEMPT Fri Jan 13 06:50:31 CET 2012 x86_64

Processor: AMD Phenom(tm) II X6 1090T Processor AuthenticAMD GNU/Linux
GPU:Nvidia 9800GT
Motherboard:Gigabyte 880gm-usb3 motherboard

Emulator: Dolphin 3.0-376 64bit
Game: Robots (Nintendo gamecube)

Robots NGC game seems to need 'EFB Copies' enabled with Textures; but disabling EFB Copies, during game play and not closing the 'configuration window' gets us full 60fps speed and no graphics corruption.

else
If we use EFB copies (*) textures; then game slows down to 30-50 fps;
or
If we disable EFB copies; then game runs at 60 fps but graphics gets garbage.

Please add some option to dolphin which would 'enable->quick disable efb copies' so that game runs at full speed without texture garbage.

Please see the youtube video:

thanks.

"Please add some option to dolphin which would 'enable->quick disable efb copies' so that game runs at full speed without texture garbage."

What exactly are you asking for?

What exactly are you asking for?

If you see the video at youtube; The robots game runs without garbage, when

  1. enable textures (opengl linux)
  2. then disable [ ] enable efb copies

  3. but when the graphics settings dialog is closed, garbage comes back to the game.

hence, I request for some option to 'achieve the enable and disable efb copies' which gives garbage less performance to the game;

  1. If we do not close the graphics settings dialog we cannot use the gamepad/joystick but we can play the game with keyboard.

Please see the youtube video (observe the mouse pointer):

Okay, got joystick working by using "Background Input" and fullscreen by NOT using "render to main window" and '2 virtual desktops' (rendering game fullscreen on 1st activity and dolphin window on 2nd activity (virtual desktop)).

Alternatively, playing game with frameskipping 1 and "Disabling External Frame buffer" makes it playble

In his youtube video, why does closing the window cause it to regarble the textures?!

#5 Updated by fast.rizwaan almost 8 years ago

The texture shadows do not move hence, i think the game speeds up. The incredibles game also behaves like this.

#6 Updated by NeoBrainX almost 8 years ago

@ parlane: We're invalidating all textures in the texture cache (including efb copies) when the gfx config dialog is closed, that's why the textures get garbled.

#7 Updated by parlane almost 8 years ago

So this is really expected behaviour ?

#8 Updated by NeoBrainX almost 8 years ago

Kinda, but then again we probably should invalidate the texture cache whenever the option changes, and not only when the dialog closes...
