980 Ti Strix - 40 FPS and Stutter (with Texture Mods)

[AureusPhoenix]

Hi Guys,

I recently bought the brand new 980 Ti Strix to play Skyrim at maximum beauty but I have some problems finding the right settings. I have the newest version of SKSE and ENB running as well as a massive amount of texture mods (combined with Skyrim Mod Combiner). Strangly, the Game is running on about 40 FPS and stutters especially when turning while the GPU is not running full load. I am typically at 60% GPU usage, under 60°C temperature and the vram usage is about 25%.

 

Can anybody tell me how to solve those problems?

 

 

Thanks a lot in advance!

Cheers!

 

PS: Stutter is most obvious near Whiterun. Thus I assume this is mainly a vram problem. I also sometimes see that the vram usage drops to zero for a short moment exactly when experiencing a strong hickup.

 

 

PPS: Other Information...

CPU: 4770K at 4.4GHz

GPU: 980 Ti
RAM: 16GB

SSD:

Game on Asus RAIDR

Mod Organizer on Samsung 1TB

Hi

 

I found it very difficult to set up a 980 ti.

 

Two of the enb ini tweaks I did to get it working was I switched on ambient occlusion & EnableUnsafeMemoryHacks=true along with ReduceSystemMemoryUsage=true

 

Here is the post I made after solving my problems.

 

For most of this year I used a GTX 980 sc at 1440 at 45fps average with ENB. The experience was totally smooth, no lag no mini freezes. I used the default settings for RealVision & set up my Skyrim inis according to the RealVision page.

I replaced the GTX 980 with a GTX 980 ti sc to get the frame rate closer to 60fps. After installing the card I loaded up skyrim I was greeted with stutter, mini freezes & freezes before killmoves, Even though I succeeded in getting 60fps outdoors my game was unplayable.

It took 3 weeks of testing to get the GTX 980 ti sc running as smooth as the GTX 980. After second week I gave up and decided to run Skyrim vanilla at 4k. That is how I solved the stutter.

The 980 ti didn't like the ENB settings in the skyrim inis. The game would pause for half a second every 5 seconds. Frame rate stayed at a constant 60fps. I replaced the ENB tweaked inis with ones I used before I stared using enb & the pauses were gone. Skyrim was still stuttering though. The type of stuttering I was experiencing is when frame rate stays constant but skyrim runs like a old movie. I decided to remove the ENB setup I had in the NVidia drives. I switched on ambient occlusion & the stutters were gone. Skyrim was now running perfectly in vanilla at 4k.

Since I had no mini freezes in vanilla I assumed that there was something in the ENB inis that would fix it. I had spent 2 weeks fiddling with these settings with 0 luck so I did some more research & found the answer on this Nexus page http://www.nexusmods...rim/mods/50214/? .

 

The line that fixed my mini freezes was.

EnableUnsafeMemoryHacks=false <-- Set to true if you have 4GB+ video card.
Overrides ReduceSystemMemoryUsage with better options for extreme users (requires ReduceSystemMemoryUsage=true)

The 980 ti is a 6gb card with EnableUnsafeMemoryHacks=true & ReduceSystemMemoryUsage=true the freezes were gone.

 

The Skyrim & ENB ini settings that I used successfully with a GTX 970 & 980 were totally incompatible with the 980 ti.

 

The moral to this bedtime story is don't give up. These problems can be fixed.

 

Later

P.S. The 980 ti don't like the Distant object detail at anything but ultra. Go figure.

Thanks a lot! I will try it a.s.a.p..

But one short question: The "EnableUnsafeMemoryHacks=true" will not introduce any risk to my savegame, right?

 

Cheers

[jones177]

This is for cards with more than 4gb VRAM.

 

Save games are not connected.

Post your enblocal here then we will see.

Yeah ... this might be a good idea. I've just tried the UnsafeMemoryHacks but I get CTD every 3-5 minutes. This allone can't be the solution ...

And here we have it:

ReservedMemorySizeMb=11264 start with 512. If the game is stable try 756 (11264 is crazy!)
VideoMemorySizeMb=6144 10240 (the formula therefor is VRAM+RAM-2048. But 10240 is the maximum value)
EnableCompression=false TRUE

[ENGINE]
EnableVSync=false TRUE!!!

[LIMITER]
EnableFPSLimit=true FALSE

[AureusPhoenix]

Thanks a lot ... I will try it after work.

By the way ... I had ReservedMemorySizeMb lower in the beginning and step by step increased it which resulted in better performance but still stable game. It just didn't solve the stutter completely. But I hope your settings will work.

Use this to set up your ins S.T.E.P. guide http://wiki.step-pro...de:ENBlocal_INI http://wiki.step-pro...e:ENBseries_INI

 

This can help as well. http://www.nexusmods...rim/mods/50214/?

 

Also make sure that Skyrim has no issues in vanilla. I use a ENBoost ini for this. The Skyrim ini I used for a GTX 970 & 980 did not work at all for the 980 ti. I went back to inis without ENB tweaks I made for a GTX 680 to get the game running well.

 

Good Luck

Hi Guys, thanks again for your help!

Yesterday I've tried a few things ... after I had to reinstall Windows 10 for some strange inexplicable reasons.

 

The new settings result in better performance (60FPS in general) but unfortunately do not solve the stutter. The only setting that reduces stutter is the UnsaveMemoryHacks. But that crashs the games in no-time. But I guess there is hope that some day, those issues will be solved.

 

Today I will test a new run of the Skyrim Mod Combiner with all Textures ran through DSopt. Maybe that helps.

I'll keep you informed ;-)
