2.5.4 Low FPS then sudden improvement

[Deano87]

Hi all.

 

I fly in VR, I have a good enough computer for the settings that I'm pushing.

 

Ever since the last Open Beta patch I've been experiencing low FPS for some indeterminate period at the beginning of the flight. It mainly happens in reasonably sized online scenarios but I will have sub-45 fps stutters and double-vision for 15-20 mins and then pop, suddenly the FPS is back up to where it should be and things are silky smooth. Its really weird. It doesn't seem related to whats going on on-screen at all. Seems to be some background issue. Nothing happens in the mission at that time to reduce the load and if I leave the server, close DCS, open DCS back up and join the server again I have the same stutters again, and I have to wait a while again for them to clear. Its all very odd..

 

Am I the only one experiencing this?

I have seen this on the PG map SP but not on the other maps (yet) I have only been on the Caucasus in MP since 2.5.4.but apart from the odd lag event it seems okay.

 

One thing I had to update my nVidia driver after updating to 2.5.4 although for me the driver was causing other random dropouts and the occasional DCS crash.

 

Although I do get the odd freeze frame which I haven't been able to find the cause of it, CPU usage normal and GPU usage well under 100% when it happens and FPS stays at 45FPS.

 

Maybe check with task manager and see if there is any correlation to either high GPU or CPU usage.

I have same problem. It happens randomly. When I look up to the sky fps becomes normal but when I look at ground it continues. After 1-2 minutes it backs to normal.

Although strangely this doesn’t happen in the Hornet. It does with the Mirage and Harrier though on PG & NTTR...although strangely not on Caucasus.

 

Weird...

Since the last open beta update I've had a steady loss of around 30 fps on average. Beforehand I used to have an average of 60 and above with my current settings, but since this update mu average is around 30 and 40 fps (strangely enough, it still runs smooth at those fps somehow, when flying).

 

Sometimes, when flying Nap of the Earth the fps hits extreme low (under 20) and starts stuttering. The faster you are going, the more stutters.

 

I've talked with couple of other people and seems like a common thing is that we all have 10 series nVidia cards. Even a person with a 1080ti said he was experiencing the same thing. I got a 1070.

 

What information should I provide ?

Game run perfectly fine and smooth before the last open beta

I'm having the same problem. When loading into the cockpit, my fps falls to 25 for about half a minute and then it goes back to normal. The same happens when I go into external or map view and return to cockpit view.

I'm noticing a performance hit myself when low among the trees. trk file provided. I used to get away with 2.0 pixel density with the odyssey with a minimum of 45fps. I had to lower it to 1.6 with the odyssey to stay above 45fps using the latest version of 2.5.4 and this track file. Can't say for sure if this started with the patch on the 16th or the latest nvidia driver, or perhaps even something between steamVR 1.1.4 and 1.2.7 I've adjusted various settings in nv control panel as well as in game, ran a dcs repair. Unsure what gives.

 

FPS is fine until I start looking at the trees or flying inverted above them.

 

Can post screenshot of my settings if needed, but would be nice to know if others are seeing a significant sudden framedrop.
