Depends on the country. Some have day before month :).

Jabo2009 hi

With your resolución 1980x 1080 for a 27 inch monitor do you can read well dígits and letters in cockpit?.

Y say that because for this size of monitor letters aré ver y blurry,so is in my case .I have a 28 inchs monitor .

You will say something about ti

Bueno

yes, all pretty sharp

Thanks Jaco

I will test it

I'm absolutly totally satisfied with these settings in VR with pixels X 1.8 and ASW auto in Oculus Tray Tool:

The MFAA and 2x Supersampling works for you? I tried it but get no antialiasing at all.

We must be agree. These settings are available for VR only. In VR only, you needn't a good AA because you duplicate pixels with Oculus Tray tool or in game. I've disallowed the FXAA to be sure that the MFAA works. I think that it can't work if FXAA is detected. To be sure, you can enable the FXAA indicator by enabling the line "toggle FXAA indicator on or off". If you see a green square on your monitor ( top left) FXAA is running so MFAA can't run.

Now, I'm not a professional. I've just done plenty of tries on the same flights and these settings are really working good for me. I make these tries above Batumi, then above Moutains behind Batumi and I end by the strip of Las Vegas. All with L-39 on low altitude. The worst FPS I get ( head turned to the right to see display moving from left to right with all hotels of the strip, and flying on low altitude over the strip from KLAS towards the stratosfear tower ) is 22 fps for the more critic situation for fps that we can meet on DCS. (Flying above the strip of Las Vegas with plenty of AI planes i've added taking-off from Nellis or heavy civilian planes moving and taking off from KLAS). In this situation, I think 22 fps is a good result. Now, above Batumi or mountains behind with high loaded forest, I have between 30 to 25 fps and all is very fluid and I havn't stutters. That's why I share my settings on the forum.

MFAA and Supersampling are two different AA method, not sure if you can have both at the same time, but they are directly linked to your MSAA setting in game.

In game: set MSAAx2

Nvidia inspector: MFAA on

This will provide you the image quality of MSAAx4 (more or less) with only MSAAx2 performance cost.

In game: Set MSAAx2

Nvidia Inspector: SparseGrid Supersampling x2

Brut AA, this will basically render at x2 your native resolution, great image quality, but heavy on performance.

MSAAx2 performance cost is already at an unacceptable level on my rig unless I turn all shadows to flat or off, unfortunately. That makes some modules unflyable with washed out canopies/instrument panels (Viggen).

Agree with you, I mainly fly the Viggen, and it's unflyable without cockpit shadow...it will be great if we can have a separate setting for shadow, I mean only enable in cockpit shadow while the others stay flat. You can try something else, wich look not that bad: if you have Reshade, you can enable FXAA and lumasharpen, the last one will remove the blur induce by FXAA, and almost 0 FPS hit. This won't remove the distant shimmering, but it's better than nothing.

Ps: default values for FXAA and lumasharpen.

D'oh... bound to happen!

Flickering

Hi!

I have a horizontal "stripe" in the middle of the screen thats flickers. I use trackir5. And when i look up and down it is ok. But if i look left and right, the stripe starts to flicker. I tried some changes in the ingame settings but nothing works.

What can i do?

Thx Phil

Btw.

is it in 2.5 any way to set up MaxFPS (FPS limiter).

Where and how :)?

Ok, found in options:

C:\Users\xxx\Saved Games\DCS\Config

in options.lua

["graphics"]

added:

["maxfps"] = 144,

Btw2.

No, it isnt good way, the same place (limit 144 RR) = 80-90fps, without limiter is here 110-120. Leave it.

Why this game have not optimization yet???

Why DCS World have not optimization yet, 6 year paas this game not have why Eagle Dynamic, we have two new map, we have alot new plain, why you dont make optimization to this game, we need optimization now please,please,please

Here are my current options for about 70 fps average flying over Vegas in the F/A-18C VFR landing instant action:

I'm playing with an ASUS GTX 1060 3GB, which I've overclocked 10%.

• Textures is Medium, because it I'm running out of VRAM if it's High in the F/A-18C.
  
• Water is Medium, which increases performance even when no water is around... which is rather ridiculous.
  
• Visib Range is Ultra, can probably go Extreme.
  
• MSAA is X2, which is almost like X4 if you're using headtracking.
  
• Anisotropic filtering is 4X. Increasing it only degrades framerates weakly, but it also only improves the graphical quality marginally anyway.
  
• The new options (Motion Blur, SSAA, and Rain Droplets) are all off until after benchmarking.
  

Thanks for this!

On the water setting when you reload from F11 Map sometimes textures load slow and you can see the water layer under all the land. It would seem all the maps are rendering a water layer even under the land.

yep... ive seen it too.

MaxFPS is useless, it does not limit to the specified FPS, but rather to a lower random one...

But setting a lower refresh rate on your monitor in Nvidia CP, does.

Ater literally DAYS of testing 50 FPS, I'm very happy with it,

with most planes, not the Harrier.

i switched from a i7 7700k@4.8 ghz to an i7 8700k@5.0 ghz , same RAM ( Gskill 3200mhz, same asus 1080ti strix), changed the PSU to a newer SEASONIC focus pro 750w platinum, changed the CASE to a brand new one Frtactal design R6.

With the i7 7700k I was able to run the game perfectly smooth at 60fps with absolutely ZERO stuttering, with the 8700k , same settings, same OS win10 build, all drivers up to date, chipset, nvme drivers, usb, etc etc.. I have a lot of stuttering.

I've tried processo lasso, changed affinity, disbled hyperthrreading, etc etc and still stuttering even at 60 fps....

Mate almost same configuration. Did you enable G-Sync through the Nvidia Control Panel (NCP)? Don't forget as well to ensure that V-Sync is disabled in game's options and in ncp settings as well.

It is essential to enable the G-Sync

GOA,.. forget everything...

1. set refreshrate to 60hz in nvidia control panel

2. turn off any gsync features.

3. do not use nvidia cp vsync settings... yet.

4. set nvidia CP options to default.

5. check Vsync in game

6. uncheck fullscreen in game

7. Test flight... you should be locked at 60fps with zero stutters..

Copy that flippin, I try that NOW.
