Low FPS and lots of tearing

[niddox]

So OpenMW have some really bad tearing and low fps compared to "vanilla" Morrowind, I even tried adding mods like MOP and Project Atlas, it helped but did not make a huge difference.

My fps outdoors in OpenMW is usually around 20-47 fps while in vanilla I get 60-70 with no tearing at all.

Specs:

Windows 10 PRO 21H1
Intel(R) Core(TM)2 Duo CPU E8200 @ 2.66GHz 2.66 GHz
4,00 GB RAM
MSI GT 710

What kind of settings do you have set?

I forgot to add but vsync also does not work

If setting v-sync doesn't work, it's either SDL not telling your driver to do v-sync properly, or your driver not listening. We don't have much power to yell at the people who might change that, and there's nothing else we can do on our end.

VSync limits my fps but does not fix tearing at all

Code: Select all

[Terrain]
distant terrain = false
object paging = false
object paging min size = 0.005

I recommend in the launcher to enable distant terrain and also active grid. Set the cell distance to 1 or even 0 (so that it's only the active cell).

You should see a noticeable performance gain.

Do some testing and report back.

Also...

Code: Select all

 [Water]
refraction = true
shader = true

Also the water shader eats GPU alive... at high settings here, it can half your FPS. If you really want shader water, then try these settings:

Code: Select all

[Water]
reflection detail = 5
refraction = true
shader = true
rtt size = 512

Managed to fix it in NVIDIA control panel by using these settings:

Triple buffering: on
Vsync: on
Power management mode: prefer maximum performance
Low latency mode: ultra
Max frame rate: 58

also changed the settings you told me and disabled water shader to increase fps, now its pretty stable and playabe, ty man

Cool! Glad to help.

Could you tell us what the before and after performance is of turning active grid off and on?

We are trying to decide if we want distant land and active grid 9n by default since it indicates to us a solid performance gain with it on.

[niddox]

Disabling the Nvidia settings and mods for more accuracy I got 20-30 fps in Balmora with distant land and active grid off and 30-40 and even 50 with it on
