FPS capped to 65 when they would reach maxFPS value from graphics.lua file

[dave_pilot]

Game version: 2.7.1.7139 (Steam)

 

Description of the bug:

if the fps would be higher than the maxFPS value in the graphics.lua file, they will be capped at 65fps. for example, this happens when i set my graphics settings to LOW, where my fps would exceed 180 fps in some scenarios, and then they are capped to 65.

Also, if i fly very high and fps are rising, they suddenly drop down to 65 too, if they would reach 180.

if my fps are below 180 then there's no problem and i really have a normal amount of fps (150fps for example).

 

this happens in the main menu and ingame and can be reproduced every time. i have included a dxdiag file.

 

i understand that fps are capped to a specific value, but it doesn't make sense that they are cut down to a third of the max fps value. i would expect fps are capped at 180fps and stay there.

Hi. I bet your custom Export.lua file is the culprit. It's located here: "C:\Users\username\Saved Games\DCS...\Scripts\Export.lua".

Rename this file so the game cannot find it, and see if it fixes your issue.

 

Here's a recent thread about this kind of issue:

I hope you can help.. I have this issue too on a fresh install of DCS on a new system. There are no mods installed and no Winwing software or similar.

If I look at the sky, the FPS goes up to 100 but as soon as I look out through the cockpit, it goes down to 45fps again, which it shouldn't.

This is my system - Ryzen 5800X, 32GB RAM, RTX 3060, Windows 10. I do not have an export.lua file (no mods) and I have tried editing the MaxFPS = false in graphics.cfg but it doesn't change anything. My settings are modest for this system, so I should, in theory, be seeing much better performance. There are no hard fps locks in Nvidia Control Panel or in RTSS, which is set to 0 on a global basis as I have a GSync monitor running at 144hz.

You should have opened a new thread since you doesn't seem to have FPS capping.

 

Try getting rid of SSAA in the game options: set it to Off instead of x1.5.

That did it, kind of. FPS now hovering around 85fps on Spitfire > Quick Start > Free Flight > Caucasus. Can you tell me why SSAA is costing me >25+fps? It shouldn't be hitting that hard. Thank you for helping by the way, I appreciate it.

Good.

Supersampling is killing FPS in DCS, that's a known fact. See here:

Thanks, it's been a while since I was last here flying... I was mixing it up with transparency antialiasing.. no need to upscale..

Yes, nowadays it's all AA this and AA that.
