Low frame rate

Hello!

Recently I was having some terrible FPS and mouse stutter issues. I was having really low FPS and mouse look in cockpit and the outside view was practically unusuable. The simulation became unplayable. I was trying to modify the graphics settings, using the lowest, medium settings and trying evey intermediate option to try to find the cause of my problems. None of this seemed to help. After hours of messing around I've managed to find a solution: pressing alt+enter. It worked wonders! Evet at high graphics setting I've got really smooth gameplay and really smooth mouse look. However, after some time the problems seem to come back, not as bad as before and doing the alt+enter trick helps to bring things back into order.

So my question for the devs is this: could you look deeper into this? Maybe it will solve problems that many us users are having from what I cam see. It seems funny that such a simple thing can do such an improvement.

 

My PC specs are:

Windows 10, AMD FX-4170 4,2 GHz, GF GTX-660 (364.51 drivers), 8 GB RAM, HDD, I'm playing in full screen @ 1280x1024 resolution.

 

Have a nice day!

change of alt+tab to alt+enter

For sure there is an issue with shadows, going from flat only to low was a terribly bad idea, the game stutters non-stop... and somewhat this is linked with the RAM, weird

 

Are devs working on a fix ? We are in this situation for many of us for months...

[ET22RULZ]

No joy here with alt+tab :(

 

I'm terribly sorry, in my previous post I meant alt+enter. Sorry for the confusion. Hope maybe this will help you.

Yep it's a know bug, currently when you start DCS World, it's displayed in full screen borderless mode, whatever the setting you choose in option tab. The only way to get rid of that is to press left alt+enter to be in true full screen mode. Gameplay is smoother with this trick, in conjunction with BOTH shadows options set to flat and flat only....even to low, it's a stutter fest.

[Theskyline35]

Yep Shadows have to be set flat only...

This fixed it! I'm back to 60 FPS. Thanks Mustang :)

 

I must add though for anyone experiencing issues with the Visibility Range values in 1.5.3, I was able to go from 30 FPS to around 40-45 FPS by upgrading to NVIDIA Driver 361.91. I suggest upgrading display drivers to the most recent one first, and then only using 1.5.2 Visibility Range settings if you still experience stutters. Your performance increase due to drivers might vary, so IMO it's a trade-off between eye-candy (using 1.5.3 settings) and smoother frame-rates (1.5.2 settings).

 

Hi MaverickET,

I'm running the same laptop as you - do you still have playable settings? If so, I'd appreciate knowing how you're managing now with the current patches, as well as a copy of your settings, if possible?

 

I'm currently running around 12-20 FPS once I get near any ground targets ... :( Any help appreciated.

Hi Divot,

I still have playable settings although I experience stutters every now and then in multiplayer. The screenshot attachment contains the current settings I'm running. I hope this helps, if it doesn't then private message me, we can further compare settings there :)

 

Also, I'm running Mustang's 1.5.2 Visibility Settings:

No tree shadow and 1.5.2 visibility help A LOT!

Hi Maverick,

 

Those settings seem to have worked - or at least made it better than it was! :thumbup: I'm not sure if the recent update/patch changed anything, either.

The only difference I made was to turn HDR off, but that just seems to be a personal preference as far as I can tell.

 

Thanks again for your your assistance,

Divot

I need to ask a question to Mustang, is it possible to make a mod to remove the tree shadow around the cities? your mod helps A LOT, but as you said, it doesn't remove shadows around the cities.

May help if you move onto a desktop as opposed to a notebook PC.

Don't know if your CPU have some kind of turbo boost or something like that, but the more ghz, the more FPS. For sure the culprit.

higher CPU Frequency = higher single thread performance = higher DirectX 11 Draw Calls Processed by DX11 API = Smoother and Higher FPS in the complex areas of the maps.

OK, a "Gaming notebook PC" :smilewink:

 

An average gaming GPU is like 4x more powerful than that mobile GPU, and a high end card is more like 8x. Still, DCS *should* be playable even on low settings. I have a laptop with similar specs and I had no problem playing DCSW 1.0.X on low/medium settings.

higher CPU frequency is not the only indication of single-threaded performance, also instructions per clock... AKA IPC...

I wonder when he got the update to stop the performance as it was before? :(

Hadwell, you could look in the hardware section of the forum. There's a quite thorough test of DCS 1.5.2 on different hardware:

There's a test of DCS with different CPU's at 4GHz:

 

 

A test on DCS performance related to CPU frequency was also made:

 

 

 

Finally there's also an interesting test of DCS performance depending on number of cores:

 

 

DCS actually scales a bit up to 4 cores.

the Intel 77 chipset wasn't stable

Which why it is always important to stress test (with a known good product for such) that the OC is in fact stable

 

Just cranking up the settings and heading off with the hair on fire... etc, etc, etc (the rave is known)

It was the 2nd to last 1.5.3 update that did it in for me, as opposed to 1.5.2 , which was perfectly playable.

 

Initial tests based on MaverickET's settings show a performance improvement in single player (with some stutters/pauses), but I'm testing it today in LAN multiplayer - fingers crossed!

^^^^ I believe Maverick runs an ATI VGA

ATi has been long dead, none of ATi's GPU's are DX11 Compatible.
