My performance with NVidia GeForce 1070

[TOViper]

What I did was making some more free space on the drive with the pagefile (yesterday 14GB, today 28GB free space), and increased the processor speed via the BIOS to 4.4GHz instead of 4.00 GHz (edit: and changed the graphics.lua). These actions made the spikes disappear ...

Hey clanitho!
Do you observe frame spikes, where the sim comes to full stop like shown in the screenshot above?
The performance - when just looking at the fps, is a bit better in MT, but these spikes make me crazy.

No spike, no stutters (or very few stutters, depending on the base I'm at)

I have the Pagefile set to a fixed size, to avoid windows resizing it in the middle of a DCS session, like this:

 

 

Also, I increased the DCS preload radius, from 50,000 to 75,000 and that solved the slight stuttering that I had when taxing in between lots of hangars. On this video (at the end of it) you can see how the framerate keeps smooth at all times

 

 

 

 

I´m getting better at landing, but somehow the Viggen's autothrottle doesn't work right when the aircraft is heavy, and the HUD keeps pointing to the left of the runway rather than down the center of it ... if this were a low visibility approach I would be crashed by now

 

Cheers,

Thanks Rudel, but I already had this since years, but that was not the point.
Yesterday I took a few hours to look in more detail to the graphics.lua.
The killers were mirrors set to ON, together with my lower setting for the pre-load radius (usually I used ~50000).

I then changed the section CameraMirrors in the graphics.lua MASSIVELY (see below), and increased the pre-load radius to 150000.
Now the frame spikes are gone.

This is what I use for the camera mirrors. Note that the setting far_clip in section CameraMirrors is IGNORED by DCS totally. You can see landscape in a distance of 50km in the mirrors, despite having the far_clip setting at 1200, therefore no clipping is performed by the graphics engine. I always wondered why the mirrors take so much performance, now I know.

thisIsMirror = true;
        near_clip = 0.02;
        far_clip = 1200;

        --structures = {100, 12000};
        trees = {100, 1200}; -- looks to be obsolete
        --dynamic = {300, 12000};
        --dynamic2 = {300, 12000,0.5};
		dynamic2 = {100, 1200,0.5};
        --objects = {3000, 80000};
		objects = {100, 1200};
        --mirage = {3000, 20000};
		mirage = {100, 1200};
        --surface = {20000, 80000};
		surface = {100, 1200};
        --lights = {200, 40000};
		lights = {100, 1200};
        districtobjects = {100, 1200};
        --districts = {8000, 8000};
		districts = {100, 1200};
        --effects = {10000, 10000};
		effects = {100, 1200};

        lodMult = 0.5;
        lodAdd = 0;

I am testing further, but the standard DCS settings for the graphics.lua, together with far_clip setting beeing ignored were killers.
