HUGE fps drop in .765

Hi my fps is usually around 120 when I'm standing in my garrison but since .765 was released my fps has drastically dropped to around 15-20 fps when standing still. even before I press start (ie run HB and select the CR and before pressing start) once start has been pressed and I start a raid/dungeon the fps drops to below 5fps making playing impossible. if I revert to .764 everything is running as it did before around 120 fps in the garrison and 60+ in raids/dungeons.

I have tried the following :- clean install of HB, clean install of WoW, no 3rd party addons what so ever, DX9 set in wow settings and all gfx setting set to minimum.

Is it safe to continue using .764 until this issue is fixed?

Heres a log from .765

by this time the fps has dropped to around 15 without doing anything else

 

Using singular the fps drop is slightly better not much tho its hovering around 22fps while standing in my garrison (still loosing around 100 fps)

here's the log

is it SAFE to use .764 for my raid tonight?

 

yes m8, every botbase every cr, every toon from lvl 100's down to lvl 1's the bot doesn't even have to be running just started (ie start not pressed) I have no 3rd party addons installed in wow, no 3rd party routines in HB and all store streaming has been turned off and its still the same 100+ fps drop when standing in the garrison and sub 5fps in raids/dungeons

I have swapped between dx9 and dx11 with no noticeable difference all ingame gfx are set to minimum

 

Great fix Tony thanks!! now if you could only put an enable/disable toggle for the overlay into the settings & tools we'll all be happy!!! Great work tho at least it seems you've traced the problem.

On a side note/issue Enyo's pause key wouldn't work either in .765 but after running the above command in the console the pause key in Enyo also works again.

OK, I'm pretty sure I've found out the main cause of the FPS loss, I'm betting everyone with this issue either uses a game launcher like 'Razer Game Booster' or they tick 'Disable desktop composition' in the Compatibility tab on the wow game icon, as this disables windows aero (with aero enabled the screen is essentially drawn twice so to improve game performance on slower PC's its handy to turn aero off) and if this new overlay feature is based on anything like Nexos's overlay plugin it uses windows aero to do the overlay rendering. so having aero turned off will drastically decrease performance when there are any aero overlay calls.

I hope this helps.
