Upgraded- Now lower FPS


Recommended Posts

I upgraded from a 7700k to a 9900k yesterday and in my first tests, I am getting around 15 FPS lower in VR. I use the F14 On Cat 5 mission as my baseline. I went from around 37FPS on the deck to 20-23FPS now. I have no idea what is the cause of this and have tried quite a few things with no difference in results. Any suggestions?

 

Specs:

1080TI 11GB GDDR5

32GB DDR4 3200

9900k

Z390E Mobo

M2 SSD

How much ram is on the 1080?

 

Did you update the drivers for the 9900k?

11GB GDDR5. The Intel support app says everything is up to date.

 

Which VR system do you have? Did not see that in your Specs.

 

Odyssey+ at 1.3 in game PD

I did some more testing and found that DCS in desktop mode is way over 60 fps and Total War: 3 Kingdoms has a 30+ fps gain. But, vr ones like Il2 and H3VR are now having FPS issues so I have no clue what is going on. They all ran smooth as butter on the 7700k.

I would also delete the contents of your FXO and metashaders2 folder under C: your user name just to be sure.

 

Also check DCS is using all the cores, I have seen the 9900 do some weird things between Win 10 / DCS. Just open the task manager to see when in game.

Download PDF Tutorial guides to help get up to speed with aircraft quickly and also great for taking a good look at the aircraft available for DCS before purchasing. Link

The difference between the 7700k and 9900k is?

 

In DCS, not much of a difference, maybe a few frames gained. The fps do seem a little more stable. I have also been using just the Tomcat and that cockpit is just a resource hog so it may actually be better. This wasn't a planned upgrade though, but I wouldn't recommend the switch for the price. I think I am GPU limited more than anything.
