Ninja buff to DX11?

Prior to the latest patch, I was trying to run DX11 on my Geforce GTX760 and for some reason the FPS was capped at 30 while VSYNC was on (and I can't stand playing with screen tearing so VSYNC off is not an option). I gave up and went back to DX9. I tried it out again recently on a lark and it is smooth as butter. Almost everything maxed out with a pretty consistent 60 FPS with VSYNC on. I've only tried it in training so I will have to see how it is in live combat.

EDIT: Just played a game on Frozen City and it held 60 FPS consistently, even with "H" vision. I have shadows on Low and Post-Processing on High, everything else Very High. This is the best this game has looked/run for me so far.

Maybe you install the latest Nivida BETA that boasts huge improvements to performance of various games ?
DX11 < DX9 performance for me so, far... Hate seeing the stutter.

What resolution and processor are you running? I'm curious about this...
(and which Nvidia driver?)

1920x1080
i5 2500K
Driver version: 335.23

I was running a Radeon HD 6870 before. The GTX 760 is a recent upgrade and didn't really see it shine until DX11. The performance increase in DX9 were not hugely noticeable.

I don't believe it is a beta driver (using 335.23). I also noticed that before the last patch, my smoke effects were green in Heat VIsion mode. That is no longer the case either. Perhaps this was a driver issue? Maybe it is the driver that has improved my graphics and not PGI.

[ShinVector]

Ohhh.. Ok yeah they did fix the green smokes and some optimization. Thought it was more of DX9 though.

As for the BETA driver... This one..

New in GeForce 337.50 Beta drivers

• Performance - Introduces key DirectX optimizations which result in reduced game-loading times and significant performance increases across a wide variety of games.Results will vary depending on your GPU and system configuration. Here are some examples of measured gains versus the previous 335.23 WHQL driver:

GeForce GTX 700 Series (Single GPU):

• 
  
  • Up to 64% in Total War: Rome II
    
  • Up to 25% in The Elder Scrolls V: Skyrim
    
  • Up to 23% in Sleeping Dogs
    
  • Up to 21% in Star Swarm
    
  • Up to 15% in Batman: Arkham Origins
    
  • Up to 10% in Metro: Last Light
    
  • Up to 8% in Hitman Absolution
    
  • Up to 7% in Sniper Elite V2
    
  • Up to 6% in Tomb Raider
    
  • Up to 6% in F1 2013

Yeah, they added a shader cache feature to the 337.50 Beta driver that caches shader files to disk. This frees up CPU cycles, which helps the performance of games that depend mostly on the CPU.

Interesting, I'm curious to try that beta driver now.

One thing I forgot to mention, I'm still using PostAA on DX11. TXAA destroyed my FPS (30 or so).

[Summon3r]

running that beta driver for 2 days now and i have seen large improvements im back to max settings across the board with shadows on high, fraps tells me im 45-58 fps avg. will try dx11 this afternoon, i was scarred to attempt it again but since your 670 is runing well with it i will try. hopefully combined with the beta driver it will work better then 30fps lol

wow averaging 57fps with dx11 max settings! this is a massive upgrade whether due to nvidia beta driver or patch in game what a difference,.... still getting the odd stutter though

I'm gonna go out on a limb and state it's a combination of your CPU and GPU. The i5 2500K is an excellent CPU, just look up it's reviews and ratings vs higher end chipsets. The Radeon 6870 was more unstable than your newer card. I began running MWO on an i3 2500k with a Radeon HD 6850 (stable oc'd to exceed 6870 performance) 8gb ram... now using the same GPU, but an i7 3770k and it made a night and day difference in gameplay... this was still during closed beta, but MWO is a resource hog. Running a dual monitor setup I can watch my widget/gadget meters for my CPU, GPU (among others) going crazy while playing the game, even while in Mechlab. The devs have also acknowledged a while back there's a memory leak in the game (unknown if fixed yet). My experience with DX11 has been positive and improved over the DX9 version.

[Matthew Craig]

We're looking closely at the Beta driver from Nvidia as well especially given that CPU is still a primary bottleneck for MWO, we don't recommend using Beta drivers for stability reasons but for the more intrepid of you I'm certainly interested to hear your findings. It would make sense that these could have a noticeable impact given we often see driver overhead very high in our performance traces. There are also further game side optimizations in the upcoming patch that should push performance higher still.

[Flapdrol]

I was trying to test if the performance improved with the new driver, but on the testing grounds with the previous driver I was 100% gpu bottlenecked, even at 1024x768.

in normal multiplayer I'm cpu bottlenecked, at a much higher resolution, no way to do proper testing.

what are your system specs

[Shamous13]

one of the guys I play with saw a 15% increase running the beta drivers while using dx9. hes running a fx4130 and an older nivida card

i5-750 on 4 GHz, I get about 55 - 70 fps.

Someone tested with a haswell quad and got about 75-100, wasn't overclocked, but turbo goes close to 4 GHz.

I managed to get dx11 to run quite fluently (60fps at all times, nvidia fps limiter), latest nvidia beta driver. Even managed to get SweetFX to work with DX11 ! Looks fantastic.
