[SOLVED] Legendary Heroes

Game:
Fallen Enchantress: Legendary Heroes

Two-year old 32-bit DX9 game. Not demanding at all. Plays a bit like CIV, top-down isometric view.

Problem:
FPS is usually solid at 60. With Reshade, drops to 5-10, even with just lumasharpen enabled. Toggling SweetFX off makes no difference, just Reshade being loaded bottoms the FPS.

Observation: The GPU usage remains unchanged (about 10-20% on a GTX680 in this early game test) when this happens, however CPU usage more than doubles, and the CPU cooling fans spin up to accommodate.

Testing notes:
Older versions of Reshade don't impact the FPS, though the game spews an error during load. Here are the Reshade versions tested and the results:

0.14, 0.15 ,0.16 ,0.17 -- FPS slowdown as described above. Effects work fine. No error reported during game load.

0.6.5, 0.9 -- Causes the game to pop-up a Windows error 'Atlas texture could not be generated'. The game is calling a file called 'DXAtlasWin.exe', which is crashing. However, closing the error pop-up the game will load fine. Additionally, SweetFX effects are applied, and there is no slowdown in FPS. Locked at 60 fps.

Reshade 0.17 tracelog: pastebin.com/9BrmUtpQ#
Reshade 0.09 tracelog: pastebin.com/thnzCUuS#

Looks like this was caused by the games use of D3DX9, which constantly attempted to get a reference to the ReShade module, forcing ReShade's hooking manager to kick in multiple times a frame (and that thing is slow). That particular issue is fixed with 0.17.1 now.

Thanks Crosire, you rock!

Edit: Just tried out 17.1 (found it on the Reshade dropbox repository by accident looking for 0.16 for Zach in the DA:I thread, are the point releases announced anywhere?) - ANYWAY, can confirm fix works! Smooth as butter again

Whoops, didn't check that. Thanks Crosire
