Topic: Poor performance

Hey, in my game I have 5 characters, each have 10000 verts and a  plant which has 30000 (The plant is not meant to have so many verts), however, I also have high resolution textures, I think 2048 * 2048.

When I go standard render and looks to the characters direction the game lags, but when I change to fixed render it goes well. Why, and has it all to do with my drivers to my graphics?

Re: Poor performance

That is a lot of verts for a plant. Is it duplicated also? A lot of game developers use tricks. Game models are usually low poly. Plants are usually made using textured planes rotated in different directions (grass usually). Textures are only high resolution when they have to be 2048x2048 sounds pretty big.

Most of the time textures are boosted for cutscenes or close ups. Even then they use tricks.

I know standard render is more dynamic but I'm not sure how it technically differs from the fixed render. I know fixed render portrays my baked ambient occlusion more accurately, however, it doesn't do shadows(which I'd have to bake as well).

Re: Poor performance

THat's why too high for characters. THe max Ive heard of is 5000, unless that has been altered in the last few years ? I'm pretty sure that's way too high just for a character . The plant is WAY too much, unless its huge and is 'vital' to your scene/game, such that it needs that many verts. WoW is a very popular game, and its vert counts are very small, and the game still ROCKS ( short of the violence which does not).

and yes,,wow definitely uses what is called 'billboards', which as TD says are textured planes rotated I multiple planes to give the appearance of '3d' as the player moves around them, and usually they look FINE.

Also, to simulate high res you could just use normal maps.

I know standard has less textures  ( short of a shader for that ?) but has shaders, whereas 'fixed' does not because its meant for OLDer GPU's.

Good luck, look fwd to seeing what you've made wink

Re: Poor performance

The plant is a single one and not duplicated, it's just a basic model, we're only testing out.

So 2048 * 2048 lowers performance compared to 1024 * 1024?

Time textures?

I see, thanks for the reply wink

Re: Poor performance

Hi, are you on linux, windows ?

your models are too high poly for sure, but if you have a speed difference between fixed and standard renderer it is most probably because your drivers are not up to date or not accelerated. For example, on linux if you don't have native AMD drivers, the rendering will be done by the CPU and not the GPU (no acceleration), same for windows. Try to install AMD drivers.

Re: Poor performance

Im on windows, alright. I'll try installing AMD drivers.

Re: Poor performance

First of all, I found out that it was my script who was lowering the performance of my game. Second, who changed my signature???

LOL! Who did??
