Summary0003116: Huge lag on intel hd 4000 when I turn the player camera left,right up or down
Description-Game runs well if I do nothing ingame.
-Game runs well if I walk forward,backyard,strafe left and strafe right.
-If using a mod that wiggle the câmera angle when in pain state, the game fps will go to 0 for about 2 - 4 seconds.
-If I move left, move right or look up and look down, the fps will go to 0 for all the moment the fps will go to 0 (plus gpu and cpu usage from zandronum will go to 0%)

-I also have a huge lag if I open the customize control,joystick options and vídeo options (When I open these menus, both gpu and cpu goes to 0% of use) and if I press esc and wait like 4 - 10 seconds it goes back to the previous menu and the cpu/gpu/fps goes normal.

-The same gpu Works fine with the latest gzdoom and qzdoom in opengl using the intel gpu.
-The zandronum 3.0 Works fine if used with the amd hd8870m

Is GZDoom 1.8.6 behaving differently?

if i have vid_fps 1 fixes this problem, but idk why
EDIT: the same happens with gzdoom 1.8.6

Also, I found that even zandronum 2.0 is suffering from the same effect but worse

EDIT: Since I can now compile zandronum, I'm gonna comiple it and try to see where things are breaking.

Tried to compile in visual studio 2017:
-Debug mode: the game took 5 seconds to show something on screen when I start a new map, but it Works without any kind of problem.
-Release mode: triggers the weird error that causes 0fps

I'm kinda lost about what's triggering this error so I may ask the gzdoom devs about some tips

in case this helps, here's a cpu/gpu log while running zandronum, til 11 seconds i was on menu, the rest i was in game:!AurELTq1jbljkbkGB-2yyHL0KBV8ew [^]

EDIT: vid_showpalette 1 also fixes the lag

EDIT 2: game start in 11 second, before that I was on menu and as you can see it's working.

ingame info:
total cpu time: external code 99% zandronum 1%
about this 99%:
46% of it is KernelBase.dll
10% of it is igdusc32.dll
4% of it is ig7icd32.dll
3% of it is ntdll.dll
3% of it is d3d11.dll

EDIT3: this problem only happens in release mode.

another log with more debug info:!AurELTq1jbljkbkHAzRdXdsbYCyxnA [^]

UPDATE: this huge lag also happens with gzdoom only in 64bits builds (all the new releases suffer from that)

UPDATE: intel has released a "new" driver to the intel hd4000.
The good part is now I can play the latest gzdoom builds just fine.
The bad is that it doesn't fix the zandronum lag iuse :(
