ATi has problems with some DX10 titles at 1080p?

[Stukov]

I have the below computer information, I connected my 4870 X2 on the bottom HDMI converted port (one closest to the board that puts out sound) to my Samsung LNS4095DX 1920x1080p HDTV. I am running Windows 7 HP with Catalyst 9.9. My main monitor is a Samsung 226BW I believe, @ 1680x1050.

I went to Catalyst CP and went to swap monitors to make my TV the main one.

I then went to the properties of the TV to change its settings.

There I saw the Hz was set to 30Hz, booted up RE5 and the TV said 1920x1080i.

Went back in to Catalyst and changed it from 30Hz to 60Hz.


Back into RE5 and TV said 1920x1080p. If you don't believe me I could take screen shots of the TV.

Depends on the adapter used. ATI makes an adapter that makes DVI the same as HDMI.

i swear i had one of those, and i searched everywhere for it, but couldnt find it, but i dont game on my big screen anyway, so its no harm, i just use it for watching movies off PC

I am using the HDMI converter that came with the 4870X2 that says ATI on it.

I wonder if that isn't different with windows 7 than vista Stukov. I've tried that in vista with no luck, as have many others.

Very possible. You can try Windows 7 out see if it works. Ive had it installed for little over a month now so I can't test it on Vista. There is a new driver model WDM 1.1 or something like that. Vista is only 1.0, could be the newer driver model makes it work better.

Back into RE5 and TV said 1920x1080p. If you don't believe me I could take screen shots of the TV.

So you can run RE5 in DX10 mode without a problem?

Remember as diltech said this issue affects alot of games, not every one though. I remember Bioshock being the only one out of my games that worked, but you had to patch to 1.02.

Did a little testing on my Vizio 47" LCD
HD 4870 512MB
4GB
Vista 64 SP2
Cat 9.9

I tested 5 games:

Devil May Cry 4 - DX10 =1080p
Far Cry 2 - DX10 =1080i, DX9 =1080p
Red Faction Guerrilla - DX10 =1080p
H.A.W.X. - DX10.1 =1080p
UT3 - DX10 =1080p

Out 5 games 4 seemed to work. Although I did have to set some of the games to 59hz or it would default to 1080i if set at 60hz. UT3 and HAWX(set to 60hz) worked without having to change any settings. Far Cry 2 seemed to be the only game giving me problems, but I think someone posted earlier they got it working with the same 59hz setting in DX10. Maybe there's a patch that fixes this issue.

Yes I can, in Windows 7, DX10 with Catalyst 9.9 on 4870 X2 on HDMI converter that came with the card on the slot closes to motherboard.

Here is image taken with a digital camera on my Samsung 40" LNS4095DX, in game settings max, DX10, 4xAA, 60Hz (also selected in game), vsync enabled, and above settings in CCC.

[Stukov]

I don't know if it matters but I am using Riva Tuners D3D Overrider in order to force triple buffering for my card. I don't see any refresh rate over rides in my settings, and it was set to 30Hz before I went into CCC and set it to 60Hz.

[TheLetterZ]

Just tested Resident Evil 5 as well, seems to be working at 1080p. So maybe it's has something to do with the game's monitor detection, I remember when we had to use refresh lock on CRTs to get the refresh rate correct.

I don't think this is just DX10, Prototype runs at 1080i and I think it's a DX9 game

[Stukov]

Works in L4D Dx9 game.


Here is WiC DX10 mode, it says 1920x1080i 60Hz. I would imagine that the issue if there is one is with some of the games.

I think 59Hz is given just in case someone screwed the 60Hz settings. You can't see the difference between 59Hz and 60Hz.

Stukov, what about setting your refresh rate to 59Hz? Will WiC work properly by then?

I guess the issue here is ATI falling down to 1080i instead of falling down to 59Hz.

[DilTech]

blind, hopefully you're right...once we're sure of the issue I'm going to document it from beginning to end, with a link to this thread, and put in my report to ati. If they can merely have the card force 59hz in games, then everyone can be happy!

Sadly, this is a fix that has to be done at the driver level, but at least we can work around for some games.

[Stukov]

I don't think my tv supports 59Hz. Is there a difference on WiC if it was 1080i 60Hz vs 1080p 60Hz?

Looks like some people fix the issue by adding HDTV modes to the control panel. If what I did doesn't work for you maybe try that.

[TheLetterZ]

DilTech,
I'm not sure it's a driver issue, the majority of games I have tried to seem to display 1080p fine. I have a feeling it has more to do with the game's monitor detection. 1080p works on Ghostbusters, Deadspace, Guitar Hero World Tour, and Demigod(altho I know they're not DX10).

What surprised me was UT3 worked without having to set the refresh rate while a few people have reported Gears or War not working with 1080p.

Edit: Has anyone tested this on Nvidia cards yet? I'm curious to see if the issue is game specific?
Can someone with an Nvidia card and those games test and see if it still happens?

[astrallite]

Aren't TV broadcasts at 59.94hz? I imagine 59hz is actually referring to that number, since it's an available resolution that pops up when a LCD TV is detected.

I use to play all the same games on my 8800GTX with the exact same set up, never an issue. None of the games I tried did I get after I bought my 4850. So as far as I can tell it's ATi specific.

Have you tried what I showed? Was that any luck?

[STEvil]

I havent run into the problem yet on my 4870X2 with XP64.

The issue could be related to the timings and info the monitor is feeding the video card maybe?

[DilTech]

I tried that before I even posted this thread... I tried every trick in the book with hours of work on it.

[nsegative]

I get 1080p in RE5, stalker clear sky and call of privat, hawx, crysis, bioshock, etc. All I had to do was add the 3 refresh rates on the first page and everything worked fine since then.

Diltech is free to try all of these suggestions but i can state for myself that you name it, i tried it. Last year i spent 3 straight weeks and altogether over 100 hours troubleshooting this issue (among others) and concluded there is no fix. The problem is simple, in dx10 mode the card is being forced to a lower refresh rate. Unfortunately no refresh rate override program will correct this

This problem is a repeat of the same issue i had years prior on dx9 with my x1950 pro when i first got a HDTV. The issue was fixed back then quite easily, Catalyst itself had an "override 3d refresh rate" tick box which forced a 3d application to use the same refresh rate that the desktop had. ATI removed this from Catalyst long ago, and third party programs as i said have no effect.

Edit: Has anyone tested this on Nvidia cards yet?

Yes! If Nvidia hadn't be the solution to this problem, i'd have given up PC gaming altogether and stuck to consoles. Fortunately it's not an issue

Well, DX10 mode isn't being forced to lower refresh rate, or everyone here would have the same problem. DX10 works for myself and others.

Have you tried reinstalling your OS fresh? Have you tried Riva Tuners D3D Overrider on your system? I have it on mine, however I use it to force TripleBuffer not refresh rates right now since it works in CCC.

It is certainly understandable to be frustrated after 100 hours, but the issue isn't DX10, or like I said no one could get it working. If it was an issue with ATI, then no ATI user could get it to work. There is another reason why it isn't working your system.

[DilTech]

D3D over-ride doesn't work with DX10. Also, for some reason microsoft removed the ability to force refresh rate via dxdiag in vista, or we'd be able to use the old ati fix.

It's a matter of it works with some games, but not all, and while the various fixes work for some they also don't work for all. The issue appears to be how the driver interacts with specific games, and can likely be fixed by AMD 100% if they take the time to do so. The more the word spreads, the more likely they are to do something about it.

Looks like a good troubleshooting thread in progress...moved to the ATi section
