Extreme lag on high end setup when driving

[ashen radish]

When driving with the camera zoomed out i get super low fps (10-15) in singleplayer b41, i tried installing the fps booster mod that loads less terrain but it did nothing at all

What PC specifications do you have? Do you have any mods enabled?

[ashen radish]

rtx 4070 r7 7745hx 32gb ram

i have ki5 vehicle mods, guns and some QoL enabled

i noticed with the task manager open that the game doesnt fully use ressources

cpu sits at 20-30% same for gpu

while i get single digits fps

[fervent shadow]

Task manager is not the best to check for resources, you have to look at the individual CPU core usage

Because if your GPU is waiting on your CPU, its a bottleneck, not a lack of resource usage

Meaning, do not look at overall utilization, look at per core utilization

[ashen radish]

tried to take it while i was full speed

enabling cpu boost seemed to help a little but the temps rise a lot

[fervent shadow]

What resolution are you running and are you fully zoomed out?

[fervent shadow]

This might indicate a CPU bottleneck in the game

Since the game is fairly CPU heavy, not GPU heavy

[ashen radish]

1440p, fully zoomed out

[ashen radish]

its weird since none of the core is fully used

and i have a very good cpu

[fervent shadow]

Does it lag less when zoomed in?

[ashen radish]

yes

in both cases i seem to get micro stutters when moving fast

like the car teleporting a very short distance

[fervent shadow]

Can you replicate it without mods on a new save in that case?

And do you have an SSD or a HDD as your C drive?

[ashen radish]

ill try

[ashen radish]

nvme ssd

in vanilla i get 30-40 fps but no drops or stutters when at full speed

[fervent shadow]

Yeah that FPS seems to be what I would expect, at that resolution + max zoom you are basically capped to 40-50 FPS regardless of specs due to engine limitations

Stutters should not happen though, so that was the weird part

I may suggest testing which mod specifically would cause the stutters in that case

The FPS booster just lowers rendering distance, your PC would likely not benefit too much from it

[ashen radish]

yeah after testing its not a vehicle stutter but the world around it

like if it was struggling to generate

i'll try to host a mp game since it seems to solve this issue

weird that running a server and playing on the same machine is smoother than a sp game

[fervent shadow]

Well, tiles need to be generated the first time they are explored

Does it happen when driving through already explored areas?

[ashen radish]

yeah ive been testing driving the same main road in rosewood
