Mythruna

mythruna is running very slow when i am playing why?

Sorry you are having trouble.  Single player or multiplayer?  Have you tried all of the things mentioned in the other threads about running slow?

it is both single and multiplayer and yes i have tried a lot of different ones.

Hmmm... those threads were not as easy to find as I'd hoped.  I was going to try to link to them.

If the slowness is because of multiplayer on my public server then it could be just that the area around spawn is full of garbage that other players have dropped and lots of tall towers and stuff.  It's the slowest part in the whole server world.

Things you can try in single or multiplayer, in order of least-debilitating to most:
-F12 three times to reduce clip to minimum
-F8 to turn on low quality shading
-try turning sound off in the game options. (may or may not help)
-Use the /trees low command in the chat bar to turn the trees ugly and blocky (but faster).
-Use the /flora low command in the chat bar to turn grass and flowers into ugly blocks.

You can also use F9 (for the moment) to turn off post-processing but that messes up some of the other effects and I don't recommend it unless it gives you significant improvement.

Also, what settings are you using in the settings dialog that pops open when you run the game?

is this what you are talking about?

Yeah, I was just checking.

What kind of graphics card do you have?  It should say in the same file you got that information from.  If you have a laptop does it have dual graphics cards (like an intel embedded 'light' card and a more powerful nvidia or ATI card?)

What kind of frame rate are you able to get?

The game engine isn't really that optimized yet, especially for older/lesser cards.  Other than the options above, there's not much that can be done right now.

Display adapter information:
Adapter:vga
Driver Version:null
Vendor:NVIDIA Corporation
Version:2.1.2
Renderer:GeForce 6150SE nForce 430/PCI/SSE2
GLSL Ver:1.20 NVIDIA via Cg compiler

Your graphics card does seem to be on the older side. I recommend doing what Paul mentioned when inside the game:
-F12 three times to reduce clip to minimum
-F8 to turn on low quality shading
-try turning sound off in the game options. (may or may not help)
-Use the /trees low command in the chat bar to turn the trees ugly and blocky (but faster).
-Use the /flora low command in the chat bar to turn grass and flowers into ugly blocks.

Updating your graphics card might be worth a try but I wouldn't expect any difference from doing so.

ok thanks i will try

Since your GLSL version reaches the bare minimum requirement, try using /flora low. (Paul, I have this feeling GLSL 1.2 was the problem with my older laptop when needing to turn flora to low.)

Well, we'll never know since the grass tests weren't run.  Only the flowers use any glsl 1.2 specific features (point sprites)... but so does the fire and the stars.  Maybe I should have a mode to pop the stars on and off to see what that does.

If that's what it is, point sprites will be optional at some point for the cards that don't support them properly.  The alternative increases the memory usage somewhat and will be slower on cards that properly support them, ironically.

If that is the case then updating to the latest nVidia drivers for your card might indeed fix the issue.

Another thing to test is if you go to the bottom of the ocean where you can only see sand and rock, basically... if the frame rate improves then you are being hit by the same thing my hobbled GeForce 6200 get hit with: texture swaps.  That will improve someday but not soon.

When I turned off flora, the waving grass stops and FPS improves x10. Are you sure grass doesn't use a GLSL algorithm to wave?

The "algorithm" is incredibly simple.  And water, fire, stars, clouds, etc. all use something similar.  Unless we can run through turning off grass separately then I can't debug this and I already posted about that more than six months ago.  So my hands are tied until I get more data.

Then having huge amounts of such wavy stuff on your screen is going to cause you problems if you have a low end computer. Unless fire was spammed on the ground like grass, we will not know.

No, you kind of completely misunderstand how GLSL works.  The vertex shader decides where the vertexes should be and the fragment shader draws the pixels.  But every material in Mythruna sets up vertexes in the vertex shader... it's just that some also move them a little.  The algorithm is not expensive.  I have no idea why the lesser cards have a problem and unless the different types of grass are tried then we'll never know... since some of them avoid movement, etc..

You: This algorithm is not expensive. My older laptop now owned by my little brother: You must be joking. *Goes into a low FPS spasm*. Also, it turns out that, that old laptop only over-heated because the auto temp regulator NEVER set the fans to high. Now my little brother can play a non-over-heating laptop at 42Cº when it's Idle... All those months of carefully measuring my temperature are now WASTED because I messed up the fan's speed when I got the thing.

You completely misunderstand me.

Math to do the grass, flames, flowers, and water:
x = y + 2 + z

Math to do EVERY OTHER MATERIAL IN THE WHOLE GAME:
x = y + 2

That's why I wanted you to run the different grass levels because I set different things on and off to see where the trouble comes from.

But if your laptop was overheating all the time then it would also be unstable and slow.  when my GPU overheats, a random frame can take 15 seconds to draw.  It's weird.

Sounds like the system trying to keep it from overheating by slowing things down. Guess it never could.

Maybe.  It could have been the extra texture look up, also.  Until I get someone else with the same noticeable "/flora low makes my performance 10x better", I won't know.

If it was just the extra texture lookup then I could work around that in a low-quality mode and still have moving grass.

98x98 texture pack?

There is so much wrong with that question. :)

The extra texture lookup is for the randomization of the waving.  I use a noise texture.

Ah, ok. Thank you paul for the knowledge :)
