If you download it and play it works. When you edit them through even his editor it crashes.

It is always the Pixel Shaders V1.1... Nothing else.

Hmm, seems to me as if the file gets somehow corrupted when you save it. Extremely weird... apart from the default recommendation to re-install everything on your machine including windows itself, I have no clue...

How isn't it the brightest idea? The Tt PSU is specially designed to only run the graphics card...

http://www.thermaltakeusa.com/Product.aspx?S=1207&ID=1500

Look at it's specs.

EDIT: Theres is different from mine for some reason... The one I have isn't a main PSU. It comes with a cable which plugs into your main PSU and then you plug your graphics card cables into it. The stats from their website should be the same.

The problem is that the TT PSU draws its power from your main PSU. Basically this means your TT PSU relies on your main PSU to feed it power as it doesn't have any independent means of getting its own power, putting your main PSU under much more additional stess than it needs to be. In even simpler terms: main PSU 520w > trying to power a "secondary" 650w PSU that has no independent means of getting its power. Logic alone says you shouldn't use a PSU thats weaker than your secondary PSU to power your secondary PSU. I'm trying to think of a simple way to explain it but suffice to say; your main PSU is being put under a lot more stress than it needs. You still haven't told me the exact specification of your system so I can't say for sure but your secondary PSU as it seems atm is not needed at all. Your Corsair 520w PSU has enough juice to run your GPU as it is.

And that's where you go wrong, it doesn't draw power from the main PSU... It plugs into your main PSU's Graphics cables to take over the graphics cards. I have two power leads going to the power sockets in the wall. Dude, it's built for this sort of thing but mine doesn't have a power-cable which you plug into the front, it is hard-wired into the PSU... I should try and find it on the web.. A video I guess..

EDIT: I found the exact one: http://www.thermaltakeusa.com/Product.aspx?C=1265&ID=1544

//World effects

is not an disabled option but a "real" comment (i.e. intended to be read by humans, not computers). Deleting the slashes (//) will lead to a syntax error, thus a pixel shader 1.1 crash. Look for the real options under that line and try those.

EDIT:
Options are those lines that start with #define, so a disabled option looks like this:

//#define THIS_IS_MY_NEAT_OPTION

whereas an enabled option looks that way:

#define THIS_IS_MY_NEAT_OPTION

Ok, but I edited that post and said that it crashed even with the normal options being taken off...
---END QUOTATION---



You still haven't given me the full spec of your system so its extremely difficult to narrow things down. Even without knowing proper specs I can tell you now just because something is "built for this sort of thing", it does not mean you need it and you can put additional strain on a system. It looks like the TT unit draws its power from the 12v rail of your Corsair unit, putting your Corsair unit under more strain. Simply; Corsair unit > TT unit drawing power from Corsair unit > TT unit passes power to GPU. The Corsair unit is still powering everything. As all I really know about your system is that its "new", has a 6870 GPU and a Corsair 520w PSU I can only assume the system isn't stuffed to the gills with additional add-in boards, optical drives, HDDs and the like. In which case your 520w Corsair unit is perfectly sufficient for your GPU and the rest of the system. The TT unit is not required. It is worth removing the TT unit entirely and seeing if your system has any stability issues.

Omg, did you read my other post? THE TT PSU DOESN'T DRAW POWER FROM THE MAIN PSU!

Do you want my full specs?

Graphics: Gigabyte Radeon 6870 Super O/C
CPU: AMD Phenom 1055T
Memory: 16 GB Corsair Vengence 1600 Mhz (Coming today).
PSU/S: Corsair HX520W Modular Main, Tt 650W Graphics power supply.

Besides all that hardware discussion you're doing here - I'm fairly convinced the problem you're having with modifying shader config files is not caused by any Mainboard, PSU, CPU, RAM, or whatever issue.

Then why when I have my old 5770 I was not getting this problem?

I'm at work when I make these posts I don't have time for detailed looks at things it would of been much faster to just say its a auxillery PSU (which in themselves have proven to be suspect to reliability questions and quality issues) One example of which is here; http://www.hardocp.com/article/2011/01/24/epower_juice_box_450w_auxiliary_power_supply_review/9. Now thats cleared up, back to the point at hand. Your Corsair unit should be perfectly capable of running your system by itself, theres nothing overly taxing in the system. Heres a comprehensive breakdown for the Corsair unit you have; http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=18

That Corsair memory will run its stock rated timings and speed and nothing more if its rated CL9 or worse. So if you were thinking about trying to ramp it up to 1866MHz I'd forget it as the chances of it managing that are slim to none. I reviewed a 8GB kit of CL9 Vengeance memory last year, to say it was epic fail would be a colossal understatement. Right now G.Skill are top dogs for memory, nomatter what plateu you are looking at.

So, in summary, its still worth seeing how your 6870 runs without the TT unit. I also still agree with Meltac, the shaders work fine theres nothing wrong with them. For anyone curious about just what exactly it is I do (yes I'm looking at you Meltac to satisfy your curiosity ) I'm a PC hardware reviewer, I've previously done some R&D work for Mushkin memory and recently Asrock with their Z68 and P67 series of mainboards and I'm also a I.T. Engineer with MCSA, and MCSE qualifications among a plethora of other certificates. So there you go Meltac, now you know

Well, I don't think it is the TT PSU. My system runs absolutely perfect on every other game and provides a nice frame rate. I wouldn't try running the system on just the 520W because this graphics card demands a lot of power.

ALSO, I was running the TT PSU on my old 5770 and it was able to run these shaders.

Well I didn't say it's not your GPU.

Try this, maybe it helps (although it's for CS):

https://www.gsc-game.com/index.php?t=community&s=forums&s_game_type=xr2&thm_page=5&thm_id=16790&sec_id=19

EDIT:
Also, have you tried uninstalling all GPU drivers and installing some older driver version? I had several issues with my two last graphic cards and in both cases it turned out that the latest drivers where not the best (at least not for the games I needed them to work with); so checking out a few (not only one) older drivers solved my issues - weird but true

You know what, it actually was the SSOA... Except I had to turn it off in the Shaders file and not in-game. Thanks!

Yes, that's what I forgot to mention; in CS you switch the SSAO in the user.ltx, but in ShoC you'll do it in ShaderSettings.txt.

Glad you finally got it working
