Use PBO to upload multiple parts of the texture simultaneously and asynchronously.

Sc4freak already answered extern xt() declares a local function xt with external linkage inside the function main(). This function never gets called, so basically nothing happens.

It is not so different in pascal... ;)

Deffered shading would definitely be beneficial in your case. As for your suggestion, the best course of action would probably be "brute-force" assignment of the lights to the objects based on the distance/attenuation/other factors; once you have done that you only need to recalculate when the...

P.S. There is, or there will be soon, it is created by Apple and is called OpenCL. All major GPU makers (Nvidia, ATI, dunno about Intel) have already announced their future support for it.

And this is the reason why I think it is pretty cool that Apple tries to force this developement. They will be integrating OpenCL into their next OS (Snow Leopard) release. This will give software developers the ability to integrate massively parallel routines in their programms. If there is no...

Maybe you are exceeding the GS max number of varyings. Also, Nvidia cards are not good with outputting large numbers of vertices from the GS. Some Nvidia employees recommend using as few GS ouputs as possible (under 20 vertices).

Ohhh, now I get it... sorry for being so stupid. I really got lost at that website...

What you say makes sense But, look at the specs sheet of 9300M at http://www.nvidia.com/object/geforce_9300m_g.html It clearly states "64-bit memory interface". A mistake?

I am not convinced. I think the info only concerns the GPU part. But the pages are really strange: 9300M spec sheet has no info about the chipset features whatsoever, while 9400M spec sheet is silent about GPU clocks...

I was refering to the information provided on the nvidia website. 9400M – http://www.nvidia.com/object/product_geforce_9400m_g_us.html 9300M – http://www.nvidia.com/object/product_geforce_9300m_g.html The bus width is supposed to mean the GPU memory interface width. I am unsure what...

Where do you have that from? Nvidia has both 9300M and 9400M on their website, for 9300M the core clocks are 400 (with 64-bit bus), for 9400M there is no clock info given but it has 128-bit bus.

And it is official from Nvidia: http://www.nvidia.com/object/product_geforce_9400m_g_us.html

Wow, that is not bad! I am rather pleased with the performance of the 9300 in the review, it seems to be sufficient for all games I was ever going to play on the MacBook... given 9400 should be faster, this is good news indeed! So I guess I will sell my few month old MacBook for a new one ;)

Let us talk only about 9400M that is supposed to have 16 cores :)
