New Cats are out, I highly recommend them if you have an X800 series card, there's a nice performance boost for CT, along with the spiffy new Hardware Shadow Mapping. Haven't had time to fully test the HSM yet, so I can't exactly tell you what it does.

Q: "Hardware Shadow Mapping" in advanced graphics settings is grayed out and I
can't enable it.

A: Hardware Shadow Mapping is supported only on GeForce and Radeon 9500+
cards if you have the latest drivers installed. Hardware Shadow Mapping
increases only the rendering performance and has no direct impact on the
visual quality of the game.


yea,I have it enabled on my 9700pro. I also recommend upgrading to the 5.4's

Shadows look a lot better now. Even the ones in Versus mode seem to have improved a little.

I have 9550 and it doesn't work even with Catalyst 5.4

HSM is grayed out for me in the game. How do you people enable it?

Note : i haven't tried the new Cats, so if HSM is enabled for these drivers, sorry... I haven't read the release notes yet.


EDIT: Ok, i've read the release notes and it doesn't say anywhere that HSM is enabled for 9500+ users in SCCT...
BTW, 9800PRO here with Catalyst 4.12

Is the overall performance for SvM any better with the 5.4? How to enable Hardware Shadow Mapping in SvM or does it make them look better just with installing the new drivers?

Hardware shadow mapping shouldn't increase visual quality, but rather improve speed. On ATI cards "hardware shadow mapping" means that they use the pixel shader to write shadows faster by using SM 2.0 floating point textures.

How do I enable HSM ? I cant find it anywhere in the Catalyst control center.

i have x800 pro with new 5.4 drivers ,
Hardware shadow mapping is greyed out still in advance options does these new drivers suppose to give support in advance options ,if so its not enabled so i can select it...

Did you enable Catalyst AI? I'd imagine the 5.4 Catalyst drivers use application detection to enable "hardware shadow mapping" in SC:CT.

Doesn't seem to work with the demo. I guess probably because the demo is not part of the APP detection or the dmo isn't updated.

Hey all. I have the cat version 5.1. Will these new drivers help at all on my 9600 Pro? I usually change to new drivers when they come out and they never seem to make much of a difference, so I didn't bother last time.

Thanks

Read the topic. You must have Cat. version 5.4 to enable HSM.

Wow, cool. I've just installed 5.4 and aparraently the single player runs better now. I did't do any benchmarks but my subjective impression tells me tht i get higher fps counts now. As mentioned before, there is no visual advantage at all

I wasn't able to detect any performance increase in SvM though. However as far as I remember even the good old Splinter Cell 1 had hardware shadow support on nvidia cards, so maybe it's still works in SvM, I just can't tell for sure. It's hard to tell just because SvM maps use only a few EchelonLights( only those cause shadows ) rest is static lighting.

Anyhow you will indeed notice a performance increase in singleplayer maps by using Hardware Shadow Mapping.

Yeah, I do notice it slightly smoother.

For some reason it's weird...playing at 800x600 4xAA and 8xAF with or without HSM is better performance than 1024x768 AA off and 8xAF with or without HSM. Usually it's the other way around.

I actually noticed a decrease in performance compared to the Omega 5.2's with HW Shadow Mapping on and off. Couldve just been my PC overheating (which it does sometimes while playing) causing slowdown.

Anyone else have this problem?

I wander why UBI didn't take the time to add support for this already. I am glad ATI takes care of it's own even though the developers don't take advantage of their hardware for some reason. I guess being a major player doesn't mean anything unless you hand over some cash. For ATI I imagine it is cheaper to just add the features themselves once the game has come out. Anyway thanks ATI!

It's actually us devs who had to add the HW Shadow Mapping support for ATI cards. It just wasn't until now that ATI exposed the functionality in their drivers, but you are welcome http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

Small but welcomed performance increase on my system. Now if only the specular highlights were handled in SM2.0 so I wouldn't have to stare at the horrible color banding... Wink wink, nudge nudge... Ah, I give up.

What method do you use for hardware shadow mapping? Render to depth texture or render to floating point texture? ATI cards don't support depth textures, but has supported floating point textures since the R300, so I'm a bit curious about the new functionality in the Catalyst drivers.

well, you answered yourself, floating point textures, using SM 2.0 to do it http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

It's not yet public information to my knowledge, so I can't disclose it without permission because of my NDA, but I'm sure ATI is more than happy to tell you about it.

I fully understand that such algorithms may be confidetial. I can only guess that ATI (and Ubisoft) found a clever way to use the floating point buffer on the R3xx and R42x cards.

Oh I see so ATI didn't work with UBI very much through the development of the game. They didn't make the capabilities of their card compatible with your game engine. Well the performance increase is appreciated.

I got radeon 9500 with V. 5.4, and the game works good. (I have Graphics MAX!!!! Accept Vsync and the resoluton)

Just updated to 5.4 yesterday to see if Hardware Shadow Mapping is really supported, and yeap, I see it in the Graphic options and performance in Chaos Theory is definitely better. I'm curious as to why this wasn't listed in the release notes or "Fixed in this driver" though.

I got an ATI All-in-Wonder Radeon 9800 Pro and I installed the 5.4 drivers. The Hardware Shadow option in the game is still unselectable. Am I doing something wrong? Do I enable this in the catalyst control center? Thanks for any help.

Great, HSM works and the game runs very smooth. The sp is perfect, the versus is mostly perfect, now just get that co op patch out and I will be 110% satisfied

When the 5.4's came out I went to the ATI home page and clicked on the 5.4 link and downloaded the package. When it was done downloading and I chose to save the file it said it was already on my computer. I thought that was weird but I went ahead and installed them. I then played SCCT and the option was still greyed out. I checked the driver panel and I still had the 5.3 drivers. I don't know why but the link was to the old drivers instead of the new ones. You may want to check and make sure you actually have the 5.4 set. If not then go back and download them again. It is fixed now. If you have the 5.4's then it should work.
