gee you would think a gtx570 would not be bottleneck by a 2500K but...

I just thought this was funny for such a dull looking game. there are spots in Fallout NV where I dip into the 50s and sometimes 40s. well even going from 1920x1080 to 1024x768 has no impact on those spots. I thought surely a stock 2500k would not be holding me back but I was wrong. of course its more of case of the game being poorly optimized but end results show that you do need to oc your cpus for some games.

anyway the game only uses 2 cores so with turbo I was at 3.5. I then raised my turbo to 4.2 and you can see the result and no more dipping in the 40s either in those spots. I resized the screenshots for the forums but these are all max settings at 1920x1080 and 4x AA.

the pics only show up properly in Chrome for some reason. they are just thumbnails in FF or IE.

EDIT: wow that was a pain in the ass but I hopefully I got it now.

IIRC Fallout 3/NV engine sucks with water and hdr effects. It makes fps slow down no matter what. If you really think that 2500k is being the bottleneck, why not oc it to 4.5?

it was just a simple test to see if the cpu speed even mattered.

He did and making his point by oc'ing to 4.2 in order to get 64fps from 55@3.5g or 8.5% gain.

55 to 64 is a 17% gain.

And 3.5 to 4.2 is a 20% gain. I really don't think it's a bottleneck, instead the faster CPU increases fps directly.

3.5 to 4.2 is 20% increase in clock but gave a 17% increase in performance. and yes it is a bottleneck. lowering the res even to 1024x768 did not help so there was no way to increase fps in those spots without faster cpu speed. its certainly poorly optimized game in spots and it takes a faster cpu to help deal with that.

You game at 1600x900 toyota and captured at quarter res? In any case, no aliasing makes this game look awesome I play with SSAAx4 and what a difference! Your shots also have no aliasing (well, a tiny bit on the hanging lights) - either you run high AA or the downsizing of the screenshot had that effect. I know it's not related to the post, but had to share

Also, interesting that a stock 2500K can still find something to work really hard on, especially on a 6 (?) year old engine. Care to look up CPU utilization at stock and 4.2GHz in this spot?

the screens were taken at 1920x1080 max settings and 4x AA just like I said they were. I already said I re sized them for the forums.

Is that in-game AA? Or are you forcing via CP?

I find that in-game one (MSAA) doesn't help with shimmering and pixel crawling. Once I started to force SSAAx4 via CCC... man, what a difference in IQ!

in game settings. the only thing I use from my cards control panel in this game is forcing vsync off. unticking vsync from the game settings does not turn it off for some reason.

NV does like CPU power.

This is a good point. I wonder if it there is anything going on with nvidia driver overhead. Too bad you don't have an AMD card to test this theory out with.

I'm getting ~30FPS in the same spot. Weird thing is my GPU is running at ~70% and the CPU load is ~50% on all 4 cores. That's on a stock Q9450 (2.66GHz) and HD5850 @ 860 / 1125.

 

[TakeNoPrisoners]

I havnt had a problem with performance really. FRAPS does lower framerates.

Then again I don't obsess over every drop to 30fps....

FRAPS has no impact on frame rates when not recording video. I am not obsessed either. I knew my gtx570 should tear through this ugly game and was wondering why the framerate was low in some spots. I would have never imagined the cpu would be holding it back though in those spots.

Lol ok.

lower your res and see if framerates stay the same.

I actually OCed my CPU to 3.2GHz (+20%). GPU usage went up to 90% and framerate went up to 35-36 FPS in the same spot (almost 20%). Seems there's something particular with this spot - I can move a bit to left or right and FPS is pegging at 60 (I use v-sync).

 

[toyota]

yeah there are a few odd spots like that in the game and I cannot figure out what causes them to need more cpu power. the same is true for the gpu in Red Faction Armageddon though where I will drop to low 40s even though nothing graphically intense is happening. it funny when you have to oc both a 2500k and gtx570 to keep framerates up in such unimpressive looking games.

Could be pre-loading areas when you move to a certain spot.

nope thats not it at all for this particular issue. Fallout will hitch a little bit when you hit a new area though.

 

[Vdubchaos]

Sounds like that game truly sucks. I can understand if it looked decent...but thats not the case.

 

[Silverforce11]

It's a great game, but with glitches. I enjoyed both FO and NV. Not as good as FO1 and 2 though.

There's a lot of mods you can use to make the game look better, high res textures and models.
