Low GPU usage

[BeNeT_]

Ryzen 7 3700X
RTX 2080TI
G.Skill Trident Z DDR4 3600 32gb
Acer Predator XB271HU 27" LED WQHD IPS 144Hz G-Sync

Sometimes the game drop to 70-55 fps using only 40-50% of the GPU. Any solution?

i dont know much about fallout 4 and how it tends to lag but you could try checking CPU bottleneck

Thx mate but;

Bottlenet calculator program: This configuration has 2.1% of graphic card bottleneck . Everything less than 5% should not be concerned major bottleneck.

Cpu isn't the problem, only work 30% max in this game. Other game work fine

In your graphics card software, set the vsync to the new graphics card vsync. For example, on the AMD cards I can set 'enhanced sync' to take over the vsync control. It then releases the FPS.

A warning, this game does not like to run over about 80 FPS as scripting errors start occurring and it will cause a lot of errors in your game. And if you run over 60 FPS, you should get the mods that allow that to occur.

The game was made to run at max 60 FPS.

Max 60 FPS

the game have problem with RTX card...disable godray and downloading performance mods somewhat helps :/

Thank you.

The game does not have any performance problems with rtx cards.
Weapon debris has to be turned off as drivers for Turing cards (rtx and late gtx) do not support it anymore.

The game has to be configured for modern hardware -

Set any "ipresentinterval" entries to 0 in the fallout4.ini and fallout4prefs.ini is a must-do. This turns off the in-game vsync which tries to limit the fps to around 60.

The control panel needs to have vsync off and the fps capped at 60 unless you install mods to unlock the fps.

This is a game engine limitation. I don't know if g-sync will also have this effect. Leave the fps uncapped and it should be around 100. Downtown however is a low fps area.

The game is nearly single-threaded. You will never see cpu or gpu usage rise to any great height. I can play in 4k with a 1080ti and i7-2600. Modded that quickly changes.

The HD texture pack can be an fps killer. Better textures exist in mods. You shouldn't have any problems on your rig.

Thank you

I have disabled vsync with "ipresentinterval". At the game runs great at 140 fps, but in areas down to 60 - 55 and only 40% usage GPU. Engine limitation obviously.

HD texture not installed. Bad reviews :)

I look mods, but i don't like lose achievements

There is a mod that enables achievements again, even for console use. lol

Not really. I am playing the game now on a RTX 3060 Ti and it performs really well. No stutters, very smooth scrolling. With all settings set to max, with the exception of Godrays are set to med ( I do not like how it looks higher ) and weapon debris is off.

But I am playing it at 1920 x 1080, with max fps set to 60. Which is what the game was programmed to be played at on a pc. Exceeding those can cause all kinds of issues.

To improve low FPS area you need to drop the old V-Sync, it was made for 60hz monitors. Use nVidia Fast Sync or AMD Enhanced Sync. Cap game at 144FPS or the same as your monitor's frequency. I suggest 144 max. because speedup will be an issue, but with this setup laggy areas will run faster.
My rig is dated 2014 and I was getting 15FPS in Sanctuary. Now it's around 45FPS in the laggiest areas, I can breeze through.

Godrays in med looks really good

I'm playing at 140 fps and at the moment 0 problems. 8 hours game

Fast Sync and 140 fps cap is really good. Thank you mate.
