Need tips for my VR setup

[clarasdk]

Hi

 

I recently decided to jump into VR (oculus rift) mainly for flight sims and Elite Dangerous.

 

I have a Geforce 1070, 16 gigs of memory, SSD disc and an old I7-2600k.

 

I can run IL-2, Elite Dangerous, Project Cars and everything else in VR just fine but I have problems with DCS.

 

Even when I put all settings on low flying over Vegas dessert with not much going on I get wierd FPS dips that leads to jutter/jumps. When I do not get these wierd spikes I run between 45 and 90 fps no problems.

 

So the question is the I7-2600k not good enough? Or what else could be the problem?

 

I have tried running the game in admin mode, I have tried deactivating hyper threading. But nothing helps :(

 

Any inputs on this topic would be great as I would love to fly around in DCS in VR, it is such a game changer in IL-2 and Elite.

Couple things that come to my mind.

 

Do you have deferred shading on? If so try it off.

What Pixel Density setting are you running? Might drop down to 1.0 if not already.

MSAA - try off first, then see if it can handle 2x.

Shadows off at first.

 

Are you overclocking that 2600k?

 

Keep in mind to, the great merge to 2.5 should be happening by the end of the month.

I have put pixel density to 1 and have tried shadow off and msaa off. Basically everything is on low or off and still I get these wierd spikes.

 

The 2600k is not overclocked as my cooler has a hard time keeping the tems low when I overclock...

 

Will the 2.5 update improve/change VR performance?

Remains to be seen, no one really knows.

Your CPU may be holding you back a little.

 

You do have deferred shading off as well?

Yep deferred shading is also off.

 

The wierd thing is that I am running around 90 fps most of the time and then suddenly there seem to come a dip.....Even when just looking up at blue sky that should be not problem to render....

DCS is pretty demanding, can't say that I get those large dips though mine is fairly consistent at least is stays 45-90 fps. Make sure you have " prefer maximum performance" selected in Nvidia control panel. I think by default it set is to " optimum performance".

 

I also run with ASW set to off.

[Cibit]

Background programs, I had severe dips with Ccleaner running in tray also causing problems was Asus AIsuite and an updater. Run taskmanager so you can see it peering from under the rift and see what is running concurrently :)

Also try to reduce the preload radius that can help

[hansangb]

Also, what version of DCS are you running? And you may want to take a look at CPUID Hardware monitor to see if your CPU is getting pegged.

i ran a 2600K at 4.8GHz with a water cooler, no problem... but definitely u should get a better GPU

[vparez]

I have a i7 7700k, 16gb ram and 1080ti and have a very steady performance of 23 fps.

 

So, count yourself lucky with your 90 fps and dips...

[Einherjer]

Everything over 45 FPS is good- don’t look at the frame counter ... just fly

 

I have a 2500k on 4.5ghz and a 1070

 

Rock solid 45 over Nevada and Normandy with setting to medium/high

You're running stuff at high with MSAA at 8x though right? Something is amiss with your game settings.

 

A 1070 should be able to run DCS at 45fps easily enough. Most other games runs at 90fps with 2x supersample and the works. DCS is a bit of a killer.

I don't agree with the GPU bit - I had a GTX970 and it ran DCSW with no issues - now I have a 1060 6GB and see no need to change it (yet).

 

imho your cpu is the problem. I also ran i5 2500k and again, no issues that others with better hardware weren't having. But I ran it at 4.3GHz. Same with my current i5 4690k - runs at 4.3GHz.

 

You need a bare minimum of 4GHz imo. Using the 2600k at standard speed will be an issue.

No. I tried everything lowest. I tried settings from Jabbers. No improvement whatsoever. The FPS in game is ranging from 15 on max settings to 32 with lowest (pixel density 1.0).

 

Totally unplayable.

Something is very wrong, Have you changed settings in Nvidia control panel ? Are you running it off an HDD, are your drivers up to date? Are you plugged into onboard graphics card by accident.

Man I would be troubleshooting the arse out of that :)

Yeah... Something's wrong. Unless you are measuring on a multiplayer server. There bad things happens. On an empty mission over Las Vegas you should be getting plenty of frames with your setup. On lowest settings it certainly shouldn't be dropping below 45 ever.

The problems are that the dips come often and makes the flying more or less impossible, every 20 secs or so.

Do you have DCS installed on an SSD? Either way, that sounds like something loading, try upping your pre-loading distance.

I don't mean to hijack the OP from their issues, but you have some very serious issues with your setup, or setup of DCS. I have a 6700k and a 1080Ti and I get a constant 45+. Can you post a screenshot of your settings

[clarasdk]

It is on a SSD and the preload radius is also set to minimum.

[lemoen]

It is on a SSD and the preload radius is also set to minimum.

 

 

So it preloads a minimum and has to keep loading more, as you fly around. Try maxing out the preload radius.

Ahhh makes sense :) Will try that.

Ahhh makes sense :) Will try that.

 

If you havent already, check this out https://forums.eagle.ru/showthread.php?t=194778 It explains a lot of the settings in detail

Did not help :(

 

I guess my CPU is just to old.

 

Cannot even try to overclock since AISuite 2 does not work after windows intel security update....

 

Guess it is time to start saving for new setup :(
