Deus ex mankind devided performance problems

[Rackooo]

Hi all!

 

I hope somebody can help me with my problem since ive been losing my mind for the past month trying to fix the annoying issuses. So the problem i am getting is in deus ex and rottr. Both games run smoothly (above 60fps), then all off a sudden just stutter terribly for about two seconds then back to normal. It is more common in deus ex tho. Im running both in dx12 with no aa.

 

Specs:

Ryzen 1600x @3.8ghz 1.25v, newest bios

Corsair vengeance 2x8gb rgb @2933mhz

Cm g650m bronze power supply

Asus x370 pro motherboard

Gtx1080 auros 8gb stock

Installed on samsung 850 evo 250gb

 

Cpu temps max 52 celsius

Gpu temps max 65 celsius

 

Tried the folowing:

-Reinstalled win 10 64 bit like 4 times

-newest and oldest drivers

-only the essentials instaled (drivers and updates)

-power plan ryzen balanced, gpu max performance and all that stuff

 

On a side note bf4, bf1, forza horizon 3, project cars, gta 5 all run without problems, normal scores while testing with cinebench, fire strike, heaven benchmarks, online pc bench tests show outstanding results

 

Plus ive read somewhere that this could be an ryzen-nvidia optimisation issue is that true?

 

Any help would be really grately appreciated!

That lowers the famerate significantly on ryzen (at least in rottr)

does it lower it below 60fps?  and it is more stable, like no more dips?

Yes in tomb raider it does go below 60 in some cases i believe that is a known issue with ryzen and dx11 in tomb raider. But with dx11 i see no more stutters just lowered fps

There is no need to reinstall the OS. My bet is DX12.

I was thinking the same. The only thing i havent tried is nvidia 378, heard that the 38x.xx cause masive problems in some games

Seems like after reading some more posts on the web that it really is a dx12 issue still with the 1080. Thanks for your answers!
