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 :(

UPDATE: I don't have the intel hd 4000 setup and I replaced it by the intel hd graphics (its even worse than the hd4000).

-> The worse about this gpu is that the latest driver for it came in 2015 and no Win10 support.
BUT, the Windows 8.1 drivers install just fine and somehow, zandronum 3.0 is playable on it.
It may be due to the last big Windows update but at any case here's the link from the driver that I'm using: [^]
This driver Works with older intel hd graphics, HD2000 and HD3000.

At any case, if you guys have this fps problem and want to play zandronum you could try installing some older drivers
