FPS Issues

Post by oli.fl »

Hi,
in my first megabase i runt into some FPS issues(dosent looks like a UPS problem).
Screenshot

Screenshot (3).png (7.42 MiB) Viewed 2067 times
in debug it looks like it has something to to with the flip[on], maybe someone could explain what that means. In some other posts i have read that it could have been a Problem with G-Sync/Free Sync, but disabeling this dosent help anything.
My PC dosent look like he is fully occupied in Taskmanager.I hope you can help me :).
My Specs: I9 11900K/RTX 3090/32GB ram.

Flip is operation of flipping backbuffer to frontbuffer (in OpenGL function SwapBuffers(), in Direct3D function Present()), [On] means V-sync is enabled in graphics settings, so this operation will wait for screen to finish displaying current image ... you probably don't want to have v-sync enabled if you want to utilize G-sync/Free-sync

Anyhow, on the screenshot you posted, it is UPS problem, as UPS is bellow 60. Train pathfinding is spiking to 50ms ... your rail network is probably very large.

Ok thanks after disabeling the trains it run better. but how can my pc not be busy? not a singel core is over 50 %

But what i am understand wrong? At the Screenshot it takes 10.152 ms to calculate one tic an for 60 UPS it can take 16,66ms. So why is it an UPS Problem?

Often the memory is the bottleneck, what are detailed specs for those? Higher clock and lower latency is better

I don't know Intel Chipset and MB. but maybe you can activate a XMP Profile in Bios. The CL Latency is also quite important.
I have 3600MHZ@CL16-19-19-39 via XMP with AMD Chipset

You could also check this benchmark comparison: f.e. on Warger 100% Map
https://factoriobox.1au.us/results?map= ... &sort=time

If you want, you could also share your savefile to let us check, what we get.

Thanks fore the answer. My Ram is C18 2x16gb.

On Warger 100% Map ive got 69 UPS.

here is my savegame, if you want to test it.

69UPS on this map doesn't sound too well. I wonder, if its really the CL18 RAM or if something different is the problem. I would have expected like 80 - 90 with your CPU. But actually, not the biggest problem.

I checked the savegame. I also have about ~57 UPS. The train network seems to be quite problematic, with lots of loops and crossings. The pathfinder is very busy from time to time. (Not always, maybe it spikes, when a new path needs to be calculated.)

Reminds me of this:
viewtopic.php?p=545030#p545030

I guess, the best is to rebuild your train network... Or maybe you can cut some of the areas, which are not used currently. The tracks between solar panels are a bit overkill.

on Warger 100% Map I have 85 UPS, but my processor is much older than that of TS.
On the TS map, I fluctuate ~ 58-60 UPS
I would remove most of the construction drones. And with laser turrets, I would have abandoned conventional turrets altogether.
And still tried to increase the RAM frequency as much as possible, well, at least up to 3400 MHz
