Pixel Shader Compilation Warning

When I load the game I get a message at the bottom of the screen that says:

Pixel Shader Compilation WARNING followed by a bunch code text.

I am fairly sure this is related to DX11.

Should I be concerned. Should I change some settings?

I am just baffled by this game now. I got a new card last year to play the new crop of games like Skyrim etc. I saw an ENORMOUS improvement in SWTOR. I dont know why in STO I seem to be taking a performance hit when every other game runs better and smoother and on higher settings. Missions I used to run a few times a day with no issues are now laggy messes. Ive started getting headaches if I play too long. Guess Im getting motion sickness.

    I get this message as well when Dx11 (beta) is switched on. The game plays fine, but I don't know if it's Dx11 or not because of the error message.

    As I mentioned in another thread, I'm also getting the graphics card is not recognised before client login. Pretty sure this is LoR related.

    I have had to reduce many settings just to be able to play. I find it VERY WEIRD that I could use the exact same settings on two different lesser cards and play without issue. I have always been one of those people saying "what lag?"

    Before LoR, I used the exact same settings I had been using for years and had no issues.

    Since LoR those settings now seem to be too intensive.

    Wondering if this is all related to them "updating all textures" and messing up viewing distances and what not.

    I have always praised this game for looking beatiful and playing very smooth. Right now I feel like I am playing with vid card from the last decade instead of one rated for more intense games like Arkham City.

    I haven't been able to tell if it actually has any relevance on the game. It's been an long standing issue however. I get it too.

    Play in DX9 mode as 11 is only beta and has always showed error messages for me. I've not noticed any difference between the 2 graphically.

    It gets very confusing. Other people and website postings all say that the DX11 IMPROVES your performance.

    Since it requires a restart its hard to really compare the performance of the 2.

    Im just tired of messing with settings I havent had to change in 3 years

    I find STO to be quite a bit more graphic card intensive then cpu. And even more so since LOR. Currently i'm using 2 vid cards running at 58% each. That would be 116% of 1 vid card. On Tribble I had to find a way to get SLI to work (which I did btw) as 1 vid card just wasn't up to the task. So with LOR and only 1 vid card people are noticing a degradation in performance.

    Whatever change they made, be it textures or whatever needs to be optimized a bit more for single vid card users. This reminds me of WoW. I started that game with an AGP vid card system and I swear I bought a new computer every 1-2 years because their updates made the game completely unplayable. You mentioned swtor so i'll mention that game as well. It's a DX9 only game. Using SLI you get zero improvement in frame rate. STO has better frame rate, less stuttering and you get a performance gain when using SLI. So coding wise STO is a clear winner. That doesn't mean that you can't optimize it a bit more. Most especially menus, as opening a menu drops your fps significantly on ground maps. The stuttering or loading of textures that was introduced with LOR needs to be addressed as well. Mostly noticeable on ground maps as well.

    What graphics card are you running? Does it support DX11? Each DX11 version requires that the hardware is able to support it in order for it to work right.

    Remember almost all games which are designed to take advantage of the latest version of DirectX automatically fall back to a safe version that is likely to be supported by *everyone*. In this case that is DirectX9 and any GPU made in the last 8 years can run DX9.

    When you select DX11 in the advanced options, you are *instructing* the game to run in DX11 mode and there is nothing automatic about it, the game doesn't try DX11 and then say "this is not, right lets fall back to DX9" like other games do. Most games do not give you this ability to make this choice.

    I suggest making double sure that your card supports DX11.

    Since LOR, directx11 in fact reduces performance and significantly increases CPU usage in alot of places.

    I tested this out on my end. Login screen on DX11 (which, I assume, falls back to DX10.1 on my card) I got 42fps, New Romulus staging area I got 13, with SSAO turned off as well as on. DX9 I got 32fps, New Romulus staging area I got 24 with SSAO turned off, and 12 with SSAO turned on.

    I'm using an ATI 4890 1GB if you're curious.

    Just made a new post about this, missed this one. The exact error I see on the loading screen is:

    Pixel shader compilation WARNING, (compile error code = D3D_OK 0x0): Shaders_Processed/Dyn/D3d/Effects/Ssao_Prepass_7718ab07.Phl (ps_4_0)

    I only see it when using DirectX11, AMD 7950, Catalyst 13.5 beta.

    It doesn't seem to affect anything in game that I can tell tho.

    I too have always wondered about the supposed benefits of using DX11 over DX9. Still not sure. I don't think I notice any difference at all, visual or performance.

    It would be nice if someone from Cryptic told us exactly the benefits of using one mode over the other.

    The only thing you need to be worried about are corrupt compiled shaders in with shadows that cause green ships and black faces on shop models. only way to fix is to delete the files under the cache folder and change the setting under trouble shooting called video card to one that references direct x 9 and not dx 11
