investigating Large performance drop in VR after updating to 2.8

[some1]

The one on the right. The left option I have on high I think.

Are people monitoring their CPU temperatures and power draw? If you are overclocking your CPU, you may well be getting into states where it is being thermal and/or power limit throttled.

And? What's your conclusion? 

If we go to those idea far we could still talk about a serious bug if on 2.7 on the same spec we had 60 deg of C on CPU, and now we have on 2.8 100 deg of C and throttling.

Guys, experiment with settings posted by fab.13 here:

For me, the right combination seems to have brought overall performance back to 2.7 levels in 2D (haven't measured fps, but the dreaded 2.8 frametime stuttering is gone for good). I know results might be different for VR users, but it's worth trying.

it absolutely doesn't help.

Looks like ED has once again neglected to fix Flat Terrain shadows this update.

 

Not all fixes are easy, suggesting it is neglected is not helpful. Thanks.

Just loving the hostility towards each other on this forum. No need for it at all. We're all here because we love flying and DCS. Yet so many people are hostile which gains everyone nothing. Peace out.

Im not trying to be mean here, but I dont think it's a bunch to ask for properly working settings. Please understand our frustration with the worse performance in 2.8. Thanks.

At least they removed those hangers and replaced them with the original ones, I was having huge FPS hits around the airfields with them.

What hangars?

[RuskyV]

The hardened aircraft shelters at all the air bases in the caucuses….

Yes, but I have the hangers from 2.7, are you saying that you still have the new ones after the patch?

[Flappie]

The "basic" Caucasus hangar model was kind of enhanced: when an argument is set to a specific value, it gets bigger. If you go to Krymsk AB for instance, you will find that some hangars are "new" (bigger), while others are "old" (shorter) because there was not enough room on the airbase for their expansion.

..please stay on topic.

My test results for the latest OB DCS 2.8.0.32937 Open Beta vs. DCS 2.7.18.30765 Open Beta is still a loss of 2 ms GPU frame time with the same setting with ALL shadows set to OFF on the "low" preset.

A quick test with the recommended procedures which are mentioned in the " alt+enter / fullscreen" thread,  which was linked above , did not help. Will try again tonight.

on 2.8.0.33006 no appreciable improvement in performance

Of course its not too much to ask, but ask without the sill comments and accusations. We know its an important fix, but it doesnt always make it go faster. Keep feedback constructive and mature.

I suggest that ED builds in performance logging so ED is not dependent on us, and can run a proper statistical analysis on what system+config gives what performance.

Building in some regression testing would also prevent the general OB public going crazy over broken stuff.

For the rift s using the OTT I set a profile for DCS and set the desktop resolution to 800x600 (only accessible as an option throught creating a profile) and then set ASW to 30hz.This gives a cap of 27FPS in game but the frame times are alot lower giving an extremely smooth experience.

I'm not sure chasing higher FPS in certain circumstances is the solution. There may be more here to do with the headsets and not just FPS

 

Hello

i have tested reducing the desktop résolution in OTT in addition to ALT-ENTER: best result i could have for now in DCS

such tips can only be used with occulus headset

I don't want get off topic but just to add if you then set the headset to 45hz in the OTT (not the profile) this can also help

Again, people not appreciating that they're on open beta.

"ED ruined my game. I can't play anymore"  

"Yes, you can. Run stable" 

(It's still on 2.7 and just as good as what you were happily enjoying without complaint a few weeks ago).

You can't test all the fancy bells and whistles of such complex software development and expect a highly polished experience.

Please stay on topic. This is about the performance drop in Open Beta, and not the very helpful advice to switch to stable. We get it, we know it.

Create your own appreciation thread for the stable branch and let people do their testing here.

[martinistripes]

I've got no problem with people doing testing and providing helpful feedback. I'm not saying switch to stable, I'm not on stable either. Just don't be on beta and be disgruntled and point fingers when everything's not perfect. It's disrespectful and ungrateful when people say, "thanks I can't play anymore" or "ED screwed things up". That's not helpful to anyone and won't make the developers feel good about all the hours they've put in to crafting this fine simulation.

You realize all multiplayer servers out there are running OB right?

First, that's not correct. There are servers that run stable.

Second, so what? If someone believes Open Beta is now "unplayable" they should take it up with the server admins. But since the majority of servers are still running OB, how bad can it be for the majority of players?

[speed-of-heat]

this is a separate though related problem ... I suggest someone creates a different thread about OpenBeta being default usage by a percentage of the community, if you want to discuss that, and it's associated theology.  This thread is about the performance issues faced in 2.8... and i suggest we keep it there.

Fair point, just tired of people using "switch to stable" excuse for a poorly polished release thats features are being marketed as the main game to the public so to speak, with the majority of major MP servers running OB. Anyways enough of that silliness and back to the topic at hand, performance of 2.8 for me is about the same as 2.7 with terrain shadows set to off from my experience. Was using flat terrain shadows before 2.8 dropped. Multicore should help quite a bit when it releases one day.

It's not an excuse, it's just a solution for people rejecting the OB inconveniences.
