Stuttering in Crysis with CF6870

mattius1989 · 20 May 2011 at 00:40

Ok, so my two 6870 1GB came today and I have set them up on crossfire. Naturally, I headed straight to Crysis Warhead.

So I cranked it all the way up to enthusiast 8xAA etc (everything on max) @1920x1080. Now as far as I'm aware this setup should breeze Crysis.

It seems I could be mistaken. As I play the game, anytime I turn around in game, I get a big 2-3 second stutter. Am I perhaps setting my expectations too high of this setup, is crysis at fault or (as I have been reading some people say to others on forums) is it my PSU? My psu is a Corsair 650W.

Any help on this would be appreciated. Thanks.

Using latest drivers and installed latest CAP?

Are we talking about Warhead or the original crysis.

The original crysis is still if im not mistaken a very demanding game, I dont think two 6870 can max the settings at 1080p.

If the warhead.. then possibly, my 5870 managed max settings at 1920x1200 with 2x aa, which was plenty, so two 6870's should handle it.

Degfrag your hdd.

Windows 7 automatically takes care of it.

I would say 8XAA is probably too optimistic for CF6870 on Crysis 1...try dropping it to 4xAA may be?

Also, it is not uncommon to get shutter on CF set up, especially when frame rate drop to sub 30fps. While 25-30fps might be fine for a single GPU, it might not be the case for multi-GPU set up...

2X 6870 1GB is not up to the job at the settings your playing.

Marine-RX179 · 20 May 2011 at 07:47

Also your Phenom II will also be somewhat a limitation, since Crysis 1 an Warhead is a two cores game...and your frame rate will be lower than people with overclocked i5/i7/SandyBridge.

Oh

lol. Ok. I turned V-sync off and that made a massive difference. But ill try dropping the AA down to 4x. Thanks for the help. Crysis is such a demanding game

Just on a side note. Might be a silly question but my CPU wouldn't bottleneck my setup would it?

Entirely depends on the game in question and whether or not it's designed to be multi-threaded.

In most cases, no, you won't be CPU bound. But I would imagine that some CPU intensive games that aren't multi threaded will suffer from your CPU's limitations.

Well, the problem is Crysis 1 is an older game that don't use more than 2 cores, so the extra cores on your X6 doesn't really help improve the frame rate and your 1050T is pretty much running like a Phenom II X2 at 3.6GHz, which is quite a bit slower than CPU like i5/i7 overclocked to 4.0-4.2GHz on 2 cores.

mattius1989 · 20 May 2011 at 13:32

Do you think this processor is a bit of a waste of time or do you think in future games it will be worth having?

Irrelevant to the issue he is having because he is GPU limited at those settings.

The processor is fine. Your most likely bottlenecking on memory bandwidth, turn the AA down a notch.

How is it irrelevent when I was simply answering OP's question? Also, I already said the main cause of the issue he's having at the moment is more to do with graphic side than anything else.

i don't get stuttering on crysis 1 but get absolutely horrendous screen tearing even though the fps is around 50 when maxed out, i have a 570 though

This bit is relevent ^

You then added this which was not relevant ^ to the OPs first post.

Not relevant to cryiss as he was asking about games in general & yet you go on about crysis again, he was not talking about the frame rates but about the stuttering. i5/i7 overclocked to 4.0-4.2GHz on 2 cores will not fix that issue with that game with his settings.

Go back and read the order of the posts again. When I made that post we were still on the subject of Crysis, and he didn't ask about other games yet. He made another separate post asking about future games AFTER I made that post.

And I don't see the point on you remark about the i5/i7, since I never suggested in anyway it will solve the stuttering. But now that you mentioned, with slightly higher minimum and average frame rate, while it will not resolve the shuttering complete, it should reduce the frequency of its occur, even if it is reduced very little and not really helping much.

I'm have not said the OP should ditch his Phenom II X6 and go upgrade his CPU/platform for the sake of some old games that don't use more than 2 cores, so don't pretend you know what I'm thinking and link what I said to what I did not say. And no, CF6870 not as powerful as CF6990+6970, so don't try to apply my opinion for that for this situation neither.

The multi quote function does them in the correct order & i have read then again.

I only manually did the first quote.

So no he was not taking about crysis as its not a bottle neck at that setting with his cards.

& you mean this one which is basically the same as bottle necking the system.

I was under the impression that his post at #8 was still regarding Crysis, since it is what this topic is about, and #11 he's asking about future games.

So you think OP asked the same question twice for fun then I guess?

I am under the impression that his post at #8 is about regarding Crysis, since it is what this topic is about.

He said as a side note & not Crysis.
Its you who gave him the idea that his CPU is not upto the job & you mentioned crysis again so he asked about future games after.

Edited: Actually none of that matters ^ semantics & lets say he was.

Possibly but in Crysis at your res & settings no.

But Your reply would only been relevant if it would have made a difference to his situation which it would not.
