LE A mod to improve performance with quad cores.

[Beriallord]

Currently my I5 2500k with dual radeon 6950s aren't doing me any good in this game because I would be hitting a CPU bottleneck, because it only uses 2 out of 4 of my cores. Meaning I cannot max this game out completely and get 60FPS, when technically I should be able to if it actually used my CPU.

 

Would it be possible to mod the game to make full use of a quad core processor? Like most other modern games?

 

Anyway here is the Tom's Hardware benchmarks that prove this:

This probably won't help much but you can make a shortcut to the skyrim launcher, and go into properties of the shortcut.

add +fullproc to the right of skyrimlauncher.exe so it'd be

 

<disk>:\<Pathtoskyrim>\SkyrimLauncher.exe +fullproc

 

right in the target box.

 

It apparently makes skyrim increase its processor priority, as if you alt tabbed out and increased it manually in the task manager.

 

Won't help you use multiple cores though.

I'll try that and see if it gets me any better on completely maxed settings.

 

I can get 60fps on basic ultra settings, using only 1 GPU, but if I turn everything up, the FPS drops in the 25-30 range and it stutters frequently. Having crossfire enabled actually gives me a drop in FPS over having it disabled, its pretty substantial, 45 FPS compared to 60. Partly due to ATI drivers, but mostly due to this game only using 2 cores.

 

On the Tom's Benchmark, the only reason SLI 460s get anything over a single one is because they are a lesser powerful card that wont get bottlenecked by using 2 cores.

 

I honestly don't even know why Bethesda recommends a Quad Core CPU when the game doesn't even make use of it.

Consider adding

 

iNumHWThreads=4

bUseThreadedParticleSystem=1

bDecalMultithreaded=1

bUseMultiThreadedFaceGen=1

bUseMultiThreadedTrees=1

 

To your SkyrimPrefs.ini

 

I don't know if it actually makes any difference [haven't compared with what happens with iNumHWThreads=2 for example, but all my cores are busy with iNumHWThreads=4, so my guess is multithreading works, but for some reason Bethesda refuses to take advantages of it].

****EDIT

 

I originally thought this worked, but I made a mistake and clicked high settings instead of ultra, and the problem persists, with or without doing that. I am really pissed I can't max this game out with the PC I got which is technically a solid PC.

 

On Ultra the game is borderline unplayable, FPS hovering in the teens at times. The Bethesda logo on start up lags, and during Fraps it shows 12-15 at the bethesda logo. I mean for crying out loud I got a top end CPU and got 2 top end GPUs and my performance in this game SUCKS.

 

What is even more pathetic is I got a 4 year old Emachines that can run skyrim on low and get 20-30 FPS and I can't even max the game out with a top end machine. Way to go Bethesda.

I originally had a big FPS issue, which turned out to be due to antialiasing. For some reason, my ATI HD 5870 didn't seem to like anything above 2x AA whenever there was smoke.

 

Setting AA to 2 fixed that and I'm running everything at 60 FPS (and I'm well beyond "ultra" settings with .ini tweaks).

It's also pissing me off.

 

 

I bought a Quad Core just recently so i can max out my games again and what does Bethesda?Gives us a straight copy paste port that only uses 2 cores.

I mean,really?

 

Fix it! :(

 

However,you could try deleting the d3d9.dll in your skyrim folder.It gave me a nice FPS boost.Still not 100% smooth because of bad port but definetly better.

If it gives you problems,just put it back in the folder and the game should run again.

Look into ENBSeries patch 0091 and wait on AMD to release Crossfire drivers for Skyrim...

 

Nvidia hit us with its 285.79 beta driver capable of enabling SLI in Skyrim, while AMD claims its CrossFire driver is on the way. It's just a shame there's nothing to show the folks looking to play this game with a pair of Radeons at launch.

 

Straight from the benchmark review you linked.

 

Also, mods to improve threading are going to be a few months away if they ever happen. Making a stable mod that function changing for a game as unstable as Bethesda is known for is pretty hard to accomplish. And good luck if you're holding out for Bethesda to release a patch to improve threading. :rolleyes:
