how does optimize work

[zehao39]

hi

I have a question about how optimize work. Why in some game there are huge difference between the and and NVIDIA. How is it work? Why the game in only advertising for gpu optimize,Not in cpu. Also the game console can have better optimization?

I don't quite understand what you are asking, could you try rephrasing it please?

like how does a game company optimize a game. How does it work?

Company X throws more money at the game developer, game developer spends more time to make sure that game works well on company X's hardware.

OP is asking why some games are more Nvidia biased (Gimpworks) and why some titles, like hitman, preform well on AMD card

ummmmm what company is AND and gpu optimiziation is just them makinng it run more efficently and better on certain api's/games

so for example with doom and vulkan AMD has focused a lot on optimizing their cards for vulkan and DX12 (and hitman)

There is your explanation.

Consoles are better optimized than PC because everyone runs the same hardware, and the company making the game can tailor to what the card is good at doing efficiently.

Ex. AMD is good at Async compute

 

pc is more powerful, but less optimized. some games run better on Nvidia graphics cards because some games use lots of tessellation, which Nvidia cards are good at.

some games, like DOOM, use low-level APIs like vulkan, which AMD supports way better

[zehao39]

so is that mean if a game is not well optimized, the game is only use part of the gpu horse power

so it is more like the game dev design a game base on some card?

When it is not well optimised it runs like shit even under full load

If a game is not well optimized for the hardware the software will take more power away from the hardware in order to complete a task that would take much less power on a better optimized piece of hardware.

for consoles, yes.

they see what runs better on the Xbox/PlayStation, and because everyone has the same hardware inside a console, they can use the most efficient code

 

this is not how it works for PC.

sometimes, GPU companies will help game developers make games, and during the help process, they make sure that the game utilizes the strengths of their particular GPU.

for example, in Crysis 2, Nvidia put a bunch of unnecessary tessellation in the water, because Nvidia cards were good at tessellating, and AMD was not. because of this, the game was super laggy on AMD cards, but fine on Nvidia cards (People call this scummy behavior Gimpworks, referencing how NVidia's Hairworks, Waterworks, and others favor their own cards)

 

the same happens from the other side. AMD also helps devs code, and some games like hitman run much better and AMD cards

Tom Clancy's: The Division - this is an example of optimization where the game developer's optimized the game so that the majority of the people can play this game with their existing hardware.GPU companies *Cough* nvidia *cough* tries to make game developer's use their proprietary code in their game's like Physx >  PhysX is nVidia's proprietary motion simulator , it's code is not open source ,that mean's any other gpu company (AMD) cannot optimize their card's to perform well because the code used in game is not publicly available since it's property of nvidia there-fore giving nvidia an edge over the other companies.this is one of the reason why nvidia has an edge over amd.

As RadiatingLight pointed out , tessellation (proprietary) is being used as a weapon by nvidia against amd. Open-source is good for us as gamer's and game developer's as it lower's performance difference between different types of hardware,but that is not likely to happen any time soon. Thanks to greed($$$)
