Here are my specs:

Model Name: MacBook Pro

Model Identifier: MacBookPro4,1

Processor Name: Intel Core 2 Duo

Processor Speed: 2.5 GHz

Number Of Processors: 1

Total Number Of Cores: 2

L2 Cache: 6 MB

Memory: 4 GB

Bus Speed: 800 MHz

GeForce 8600M GT:

Bus: PCIe

PCIe Lane Width: x16

VRAM (Total): 512 MB

I'm aiming for 60FPS. I'm drawing textured triangles. which are alpha blended:

glVertexPointer(3, GL_FLOAT, 0, &m_vertexArray[0]);

glEnableClientState(GL_VERTEX_ARRAY);

glTexCoordPointer(2, GL_FLOAT, 0, &m_texCoordArray[0]);

glEnableClientState(GL_TEXTURE_COORD_ARRAY);

glColorPointer(4, GL_FLOAT, 0, &m_colorArray[0]);

glEnableClientState(GL_COLOR_ARRAY);

glDisable(GL_DEPTH_TEST);

glEnable(GL_COLOR_MATERIAL);

std::cout << "Drawing " << m_vertexArray.size() / 3 << " triangles." << std::endl;

glDrawArrays(GL_TRIANGLES, 0, m_vertexArray.size());

glDisable(GL_COLOR_MATERIAL);

glEnable(GL_DEPTH_TEST);

glDisableClientState(GL_VERTEX_ARRAY);

glDisableClientState(GL_TEXTURE_COORD_ARRAY);

glDisableClientState(GL_COLOR_ARRAY);

I can't seem to render more than 2000 triangles without running into performance problems. This seems fairly small. Is this just something I'm doing incorrectly?

Kind regards,

Samuel
