Help with Crysis (please)...

[penske2298977]

My system:

Vista 64, sp1 (all latestet updates aside from sp2), 6 gigs of RAM
i7 940 @ 3.5
ATI 5970 x 2 (quad xfire)
Creative x-fi
All with latest drivers.
I am trying to play at 1920 x 1080 with 4X aa at "High" settings (under DX10)

But for some reason Crysis runs extremely slowly under DX10 --- if I repeatedly reload a save game (return to menu reload etc...) it will then (rarely) run ok. But typically anytime I load a game or start a new game it will run extremely slowly (as in slideshow slow).
However, under DX9 eveyrthing runs perfectly fine.
I have tried reinstalling Crysis, using different Cat drivers from 10.6 - 10.9, different settings, updating DX runtime, defragging etc...nothing seems to work.
With the same setting noted above there are no problems with the game whatsoever under DX9.
Anyone have any ideas why under DX10 the game seems broken (at least for me)?

Are you playing on a HDTV? Or perhaps connect to your LCD through HDMI? My Radeon was forcing 24Hz on my HDTV when in fullscreen DX10 mode in Crysis and a few other games. Hence you could only see up to 24 FPS and the games felt slow (not to mention the pain on my eyes ). When I was going back to DX9 mode everything was fixed. There's a way to solve it for DX10, but let us know the answer first

I am playing on a 27" LCD (TN panel) monitor from LG. The correct .inf is installed...under DX9 everything works great. Why DX10 completely chokes my system is odd --- other games (either dx10 or 9) work fine. But I am really stumped why Crysis under DX10 on my system/hardware is seemingly borked.

 

[penske2298977]

if I was unclear, it is connected via DVI...also I am using a DVI KVM switch to switch between PC's could that be the culprit?....haven't though of that until now when you mentioned possible display problems.

Can you start up Crysis in DX10 and see the refresh rate? There should be an option on your monitor to display current monitor mode.

might find help at www.incrysis.com

 

[penske2298977]

Yes, I could do that (at work now though) but vsync is disabled (in game) and the default "refresh rate" for the monitor is 60 hz.

 

[penske2298977]

Thanks for the link, but I have scrubbed though incrysis.com and the web in general and came up empty...so I thought I would post here...seems like there is something really idiosyncratically wrong with my setup (solely with respect to Crysis under DX10)...it seems as though I am at a dead-end to deteremine what it might be...I guess I'll have to stick with DX9.

Well, so is my HDTV. 60Hz. And v-sync has nothing to do with it. A 24Hz refresh won't allow you to see more than 24 FPS, even if the game engine runs at more. V-sync will force the game to run at specific FPS, connected with your monitor's refresh rate. In your case it would be 24, 12, 8 and lower and only those numbers (provided your screen was forced to 24Hz). That's just a general explanation, not really relevant here.

If the game's not forcing to run your screen at a very low refresh, I'm out of ideas. I had a similar thing in Crysis and Trine (very low performance cause my HDTV was forced to 24Hz) and also own a Radeon 5-series. Also, I can play both Crysis and Warhead comfortably at 1920x1080 AAx4 Very High / Enthusiast DX10 on my OCed configuration. Your quad fire should slaughter it.

 

[penske2298977]

I'm not sure how or why Crysis could be forcing and/or detecting a low refresh rate --- but I have been using a DVI/KVM switch (possible culprit?)--- when I get home I will hook up the PC directly to the monitor and see if that makes any difference. I will post if I have any success.

 

[Atreus21]

Probably a misinformed question, but have you tried a different monitor, or a different video card?

 

[penske2298977]

I have not tried either --- but I may try that next and/or not using the DVI/KVM switch.

 

[Fenixgoon]

have you tried using only one of the X2 cards? maybe quadfire has driver issues with crysis.

 

[penske2298977]

I will pull one of the cards tonight --- however, to re-state. In dx9 eveyrhting is fine, only in dx10 is it a slideshow. But I am aware that Cysis scales poorly (if at all with xfire). But that still doesn't explain the difference I am seeing between dx9 and dx10...something is wrong...either hardware or software. Will try to sort it out (again) tonight).

I seem to remember it being an issue of trying to run HDMI resolution without using an HDMI cable. I think it was part of the DRM scheme used in HDMI which kept HDMI monitors from running at HDMI resolutions without using a HDMI cable. I had the same issue with another TV, but running it with an HDMI cable fixed the problem.

EDIT: If it runs fine in DX9 at that resolution, then it probably isn't the issue I am thinking of. You can feel free to ignore my post.
