How Can I Get Me Integrated And Dedicated Card To Both Work At The Same Time

Is it possible to use both integrated graphic card and a dedicated one on a Laptop for running one game?

Not at all. The reasons are-There is no hardware link between your 2 GPUs like SLI or Crossfire. They are present on the same motherboard, but they are not connected to each other, which does not allow splitting up of workload.There is no driver support for integrated and dedicated GPU like SLI.Games don’t support this type of system.Huge performance difference between these 2 GPUs, due to this most of the work needs to be done by the dedicated GPU, so running them together will give almost no performance gain.In some games, when I tried to play them with Intel HD 630 (a new and powerful integrated GPU) instead of MX150, some objects, people, sometime some cars were not rendering correctly, maybe due to bad software support and lack of optimization. So making them work with dedicated GPU, might result in a badly rendered frame or even decrease performance.

Can I in some way use both dedicated graphics and integrated graphics at the same time in a game to boost FPS? If so, how?

That entirely depends on the API used by the game. Any DX12 game which implements exclusive/explicit multi-GPU support (which is not SLI or CrossFire) can utilise both graphics card at the same time. However, vendors must expose said feature in their WDDM2.x driver on Windows 10.Afaik few games actually implement this feature but expect more titles to support it in the coming years. I believe Vulkan also offers this feature but almost no game is using it, at least not on Windows. AMD also supports their own proprietary dual-graphics solution on select APUs but that itself has limited benefits.Btw, integrated GPUs will bring almost no performance improvements, even when used in that configuration because they are not designed for gaming in the first place.

Can I use both integrated graphics and dedicated graphics at the same time on my laptop for gaming?

Short answer is no, and you wouldn’t want to anyway.Main way to use multiple GPUs is Crossfire for AMD or SLI for Nvidia. Both solutions require the same brand. Both solutions function by having the same information on each card and rendering alternating frames. I believe Crossfire will allow you to use different cards as long as they’re both AMD, but you’ll be slowed down to the slower card. SLI requires the same GPU to function.Another way that’s more rare is Physx from Nvidia. Nvidia still requires both cards to be the same, but the second card will be used to calculate physics operations and such. This will only work for games that allow it and the list of those games is somewhat short.The final way is using the new feature of DirectX 12 that allows you to scale your performance across GPUs. The problem with that is that the developer has to actually use it, and virtually no games are doing this yet.In any of the use cases, your integrated GPU is probably bad enough that it would seriously drag down your performance. You dedicated likely can do physics and everything else faster than the integrated can do physics. In the scaling, the integrated wouldn’t be given a heavy enough workload to matter. In Crossfire or SLI, your integrated wouldn’t be able to keep up to render every other frame and you’d have serious issues with your framerate.So even if you could use one of those technologies, it would suck for your integrated card.

Can we use a combined integrated and dedicated graphics card on a PC?

Manufacturers are always playing with the concept of using a desktop's onboard video chip along with a dedicated graphics card. I've heard of Intel making a few attempts but I definitely know of more than a few instances that AMD has worked with motherboard and video card manufacturers to set up the framework. Also they have an APU line of processors with a GPU built in that you can augment with a dedicated graphics card.Before the APUs they had a system that combined the dedicated graphics card with the onboard graphics Chip's processing power on their Phenom II platform called Hybrid graphics. Unfortunately, both these systems weren't very powerful and returned limited benefit for the effort. One of the restrictions you had to put up with when using both systems you had to get specific video card types for it to work.Bottom line is, if you're strapped for cash you could wring a little bit more performance out of your computer with the right video card. But if you're looking for serious performance for gaming and video rendering, stick with the old formula that works.

Is the use of integrated graphics with dedicated graphics harmful?

You cannot use both of them simultaneously. Integrated and dedicated graphics are two different things. Integrated uses your ram as the primary memory for all the tasks like watching a 1080p movie or little bit of multi-tasking but the dedicated (discrete) uses its own video memory for gaming or high multi-tasking and doesn't use the system ram.
