[solved] When you're having 40FPS instead of 300FPS with a gtx 1080

Lilliedx

After using the pegasus from Velika to Allemantheia the FPS drop from 100 and stay at 40 all the time.
If I lose the game window focus (alt-tab), FPS is back to normal.
That issue is occurring on windows 10. It happened in 32bits version too.
On windows 8.1 (dualboot, same computer) it's working without problem.

Since I have a gtx1080 that's working properly on a decent computer, I have no idea on what's going on. Temps are good, any other games work just fine on win10 except TERA.

Windows 8.1 has no issues at all so I'm playing on it but still. Does anybody has the same issue? How did you fix it?
Thanks for any infos regarding that FPS drop.

Ok I found something random.

Each time I lose the focus of Tera's window, I regain my lost FPS.
But once I have the focus on the game, the FPS drop.

Anyone got that issue too ?

I'm consistently getting 20-30 FPS on an RTX 2060. The game keeps auto-adjusting me down to preset level 2.

Okay, for some reason, hitting "Reset all" seemed to help. I was already using the default setting, so that shouldn't have changed anything. But whatever.

Now I mostly get a decent framerate. But I still get random very low dips even though my GPU never goes above 50% utilization.

Lilliedx

I see. It's a different story for me, generally when your game is in background (when you ALT-TAB for example), the FPS may be lower.

My big issue is it's all the contrary. The game stays at ~45fps whatever I try to do (changing resolution from 4K to 720p, changing the settings to the lowest ever, staying in an empty place etc.) and it goes back to 144FPS when I lose the focus, when I click outside of the game window.

I can show that with screenshots eventually.

1 - I just run the game, take a pegasus and fly. The first minutes everything is fine.

2 - I take the pegasus and leave the place then during the flight FPS go to 45 and never goes above !!!

3 - If I Alt-Tab the game, my FPS are back to normal

4 - If I'm back to the game window my FPS are super low...

I have sort of similar issue. When I start the game all run in about 80 fps. After couple of hours drops to 5-10 fps, regardless of the area I am, either fishing or doing missions. Only solution I've found so far is exit game and wait launcer button turn from playing to play.

Just because you have a 1080, that won't mean you will have 300 FPS. I don't think your graphics card is the issue.

I think your issue is your CPU. Your CPU is what might be bottle necking your performance. I suggest you research your CPU.

Your RAM can also impact performance.

I run a Ryzen 9 3950X (16 core 32 thread) CPU, with a RTX 2080 Super, with 32GB of DDR4 3200mhz RAM, CL18 sadly. I barely get 220 FPS max. I think I seen 230 FPS for a few seconds but that is all. When I am in more populated areas like Highwatch, it drops to 170-180+ FPS.

You should read my previous answer, maybe you'll understand with screenshots what exactly the issue is ^^

Research your CPU. Older models tend to bottle neck very easy.

If you don't want to look in to your CPU bottle necking your performance, then the only reasonable scenario is your 1080 is faulty somewhere.

I was wondering why would it bottleneck on Windows 10 (in a resolution of 720p) and not in Windows 8.1 as I said I'm dualbooting on the computer.
And above all, why would it regain all the FPS when the game is not focused.

CPU is i7-6700K

Lilliedx

The game is suddenly having a +10ms frametime which results into an amazing FPS drop.
There's absolutely nothing related about a bottleneck as you can see from the stats taken with MSI afterburner

When TERA is in foreground : 45-50FPS with 16-17ms frametime

When TERA is in the background : 130-144FPS with 6-7ms frametime

ManBravo

I honestly think it's you're CPU. My i7 3770 with GTX 1050 TI was getting 50-60 FPS. The FPS would drop when certain effects loaded on the screen. Your FPS seems like it was having the same issues as my older PC. Your CPU is also 5 years old.

From the CPU specs, the 3770 and 6700 look very similar.

Something is definitely bottle necking your performance. My thoughts are on your 5 year old CPU.

I am thinking maybe it is the intel core. All of Intel CPUs have one thread that boosts to the maximum 4.2ghz. Same as with their other newr CPUs like the 10900k. Only one thread boosts to 5.3ghz while the other remain at 3.7 or whatever the base clock speed is.

AMD CPUs are capable of multithread boosting/overclocking. I think the Ryzen 9 is capable of all thread boosting/Over clocking.

I honestly think Intels single thread boost is what might be bottle necking your performance.

I appreciate you take your time to reply, thank you.
After testing the results I have when I switch for windows 8.1 cannot confirm it is a CPU problem.
I'm using MSI Afterburner and took the time to show you the screenshots, so now we can have a real talk.

WINDOWS 8.1

On Windows 8.1 I'm playing all the time (for hours) at a 4K resolution of 3840x2160 where I set all the graphics to the max except anti aliasing and I never have any issue at all. An i7-6700K paired with a GTX 1080 is an excellent choice as I expected from the day I bought them.
Now check the screenshot above. The %usage on the top left corner are as follow :

- GPU usage is 99%
- CPU usage is 51% with one thread reaching max 77%
- Framerate is 125FPS
- Frametime is 10ms max
(note: weird usage of the SWAP memory. I have 32GB DDR4 fyi)

Let's go back to Windows 10. Check the 2 screenshots below. And please read the values

WINDOWS 10 before the frametime bug :

WINDOWS 10 after the frametime bug :

There is no telling what's going on. I now think it is more an optimization issue than a problem from my computer.
By checking the process I didn't find anything that was running in the background impacting my frametime/FPS,
it's just TERA that decides to not run properly on Windows 10. Plus it also changes and lowers my settings instead of keeping mine by default.

AND FINALLY... if I decide to ALT+TAB the game, my FPS are back to normal when I lose the focus.
When I ALT+TAB again to go back to the game, the FPS instantly drops to 45... I'm having headaches here.

That's pretty annoying, Windows 10 being heavier with updates after updates, TERA being using an old engine to run.

ManBravo

Might be an oversight by EME on the 1080 optimization.

That is weird that it would do that and usually it's the CPU that causes that. Unless you need a fresh install of Windows 10. Have you tried reinstalling Nvidia drivers? Don't update them, reinstall with the newest version. Other than the CPU, the only other problem might be the drivers.

Lilliedx

Yes, I've deleted them and reinstalled them ( "new install" ) of the latest nvidia drivers. Nothing changed, I feel the last test will be to format the compy and make a clean install of Windows 10 then run the game and give a conclusion.

I'll tell you the result tomorrow since the Windows 10 update process may generally take some time. (It's late here)

ManBravo

Could it be your monitor's refresh rate?
