Description
Hi,

We need a very experienced DirectX consultant to help us with our game capture performance issues.

We have several problems we need help with. we will list here only the first one. If you understand the problem and can provide some insight and solutions, please apply and provide some code examples and ideas that could help us determine that you are the one.

Here is the first problem. Our game capture app needs to copy backbuffer data to memory. We first
GetBackBuffer, then CreateOffscreenPlainSurface (with
D3DPOOL_SYSTEMMEM), then GetRenderTargetData from the backbuffer into
the offscreen surface, and then - alas - LockRect the surface and
memcpy the bits.
Everything takes really fast, except one thing: the LockRect. it takes
around 50ms, on some games.
How can we optimize this?

Thanks much,

Lior

Firstly thank you for taking time to read my proposal. If I can just take a further few minutes to explain who I am and what I do and then I can discuss your project from the brief you have provided. We can show you demo very similar to your requirements, We are working into the field since last few years, We have completed more then 5000 projects successfully. If you want to see demo, please reply me My role is to communicate with you throughout the project and to understand what it is you require. With no project the same it is important we work closely with our customers to ensure the success of their business. Your project will be placed with 1 of our 10 design staff each knowledgeable in different design methods. I have read through your specification and it appears that this would be a project we would be very interested to work on. Unlike other users I would like to talk directly about your project and not simple just past a lump of text and a few links (based on what I have read on the brief). I am just trying to take time to make contact and if you want any further information or sample sites please let me know. I would like to discuss this and hopefully complete this project for you. We do not have any problem to keep money escrow at getacoder and release on progress of the work; we will be responsible for your satisfaction by our work. Kind regards Ashok Mxicoders Software Solutions Ltd

Hi Lior, We are a game development and outsourcing company from Romania and we believe we can optimize your code for your DirectX buffer capture project. Of course, that can only be done if you are not running into hardware or windows drivers' performance issues in those 50ms cases. Please check PM for details. Regards, Tudor Tihan
