Description

Game Name?

Conduit 2

Game ID?

SC2P8P

What's the problem? Describe what went wrong in few words.

  • Game runs at a fraction of normal speed despite high FPS
  • FPS is often > VPS
  • As FPS goes down, VPS goes up.
  • Increasing GPU rendering load (EFB->RAM, antialiasing, 4xscaling etc) makes the FPS go down but increases game speed
  • Frame Skipping has no effect
  • Idle Skipping needs to be turned OFF for single player to work
  • VBeam Hack needs to be turned ON to stop sound crackling, but game runs at around 90% speed

What did you expect to happen instead?

  • Normal relationship between VPS and FPS (as VPS goes down so does FPS and vice versa)
  • To be able to play game at full speed on appropriate hardware as it isn't that CPU nor GPU demanding

What steps will reproduce the problem?

  1. Run Game, any mode - note slow speed/high FPS
  2. Set idle skipping to OFF, VBeam to ON, IR to 4x and EFB->Ram, frame limiter to audio
  3. Play Game again but at constant ~90% speed.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
Every SVN revision between 4.0-1126 and 4.0-1304, 3.5-1124 and 3.0

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

No - 3.5 and 3.0 do not seem to be able to achieve full speed with any settings and the vbeam hack causes strange behaviour

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Q6600 o/c 3ghz, Radeon 6850 o/c 850/1200, 4gb DDR2 SDRAM, Windows 7x64 latest drivers

Are you using the 32 or the 64 bit version of Dolphin?

64-bit

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
