GPU underclocks too far

[Ivory]

Ahoy there LTT community!

 

Short version:

How can I prevent my GPU from underclocking itself too far while keeping Vsync and FPS Limiters active for lagless 59-60 FPS without screen-tearing?

 

Long version:

I noticed this problem recently while playing Skyrim SE with enabled frame limiter (~60) in the Nvidia drivers. Inside interiors when there's not much to render my GTX 970 underclocks itself very far.

Which wouldn't be so bad, but when more stuff appears on screen (light sources, enemies, etc.) then the GPU ramps up and causes stutters while doing so.

But most annoying of all is that it sometimes it stays underclocked and delivers subpar 30-40 FPS in these interoir situations. Unacceptable.

 

I monitored these clockspeeds with MSI Afterburner:

Outside - 1190 Mhz (base)  to 1392 Mhz (boost).

Interior normal - ~ 950 Mhz

Interior laggy - ~ 650 Mhz (<-- what the hell?)

 

Now, how can I tell my GTX 970 not to slow down that much?

 

I did pinpoint this occurence to the frame limit option in Nvidia Inspector, but I don't want to turn it off because the ingame Vsync option (iVSyncPresentInterval in the SkyrimPres.ini) causes too much input lag for my tase.

Therefore I limit the framerate to 59 or 60 and force Vsync on both in Nvidia inspector so I have pretty much no input lag and also no screen-tearing on my 60Hz Monitor.

 

I didn't notice any problems with power consumption or heat so I'm sure there's no throtteling going on.

I belive my GPU just "relaxes too much". I'd like to set a limit for how far the card may slow down in this game. Is that possible?

 

 

Hope you guys can help and have a nice weekend!

disable the fps limit in the nvidia settings? bethesda updated sse a while ago to fix the vsync going over 60,should be fine now unless you did something with the config

Well then I have smooth frames but noticable input delay.There's nothing else that I did to the .ini file.

Open Nvidia Control panel -> Manage 3D-settings and change the power management mode to maximum performance.

Hey wow! I think that is it. Gotta test it some more but the clock speeds look great, no more undeclocking.

 

Thanks man! I hope you have a great weekend
