Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Graphic Card Compatablilty Issues

I recently installed Ue4 on an old pc i have just for kicks to see if i could possible get it to run until i can get myself a better more suitable machine. Everything installed fine but when i try to run it i get a message.

WARNING: Known issues with graphics driver

This installed version of the AMD graphics driver has known issues. Please update to the latest driver version.

ATI Mobility Radeon HD 4200 Installed: 8.632.1.2000 Recomended: 16.60.2711.0

Im aware that the pc itself doesn't have nowhere near the power to run certain things but i figured it has enough to dilly dally with until i got something better to work with. Its a toshiba satellite l645d-s4040, windows 7 64 bit, 4gigs of ram (which ive seen other users use), AMD Athlon 2 P320 Dual Core Processor 2.1 GHZ, and its got direct x 11 installed. I could see my power being an issue but it seems somehow the graphics card isn't good enough. When i do manage to get a better pc in the future how will i know if my graphics card will be good enough because all the unreal faq says is "a DX11 compatible video card" which apparently mine is and its an issue. I see they have a list of ones they recommend but if i find a pc that doesn't have a card they suggest how can i make sure its gonna work with unreal before i buy it?

Product Version: UE 4.18

As far as I know, only ATI cards from 5xxx up support DX11. That does not apply to your card. Besides, it is an order of magnitude below the necessary power.

Also, while UE4 running on 4GB of RAM might be somewhat usable, do note that this memory pool will need to be shared with the onboard video card in this case.

Once you find something that fits your budget, post it here. There's a quite a lot of older video cards on the market that will have respectable performance.

Im at a loss though lol. I have directx 11 installed how can it not support it if it let me install it? The part about the memory pool was a bit beyond me you'd have to noob it down for me. I'm not the greatest with pc hardware if you cant tell. It seems to be running quite well at the moment but i haven't really tried to push it. I guess ill just have to take your suggestion into account and check here once i find something i can afford. Thanks for the help.

You can install any sort of software you want, if you really push it you can install a driver for the wrong video card - and it will definitely not work. But hey, you have it installed!

Your card supports up to DirectX 10.1. In addition, it is unsupported in Win 10 - there is not even a driver available as the support has phased out years ago. But that's not a problem at all.

The part about the memory pool [...]

Fully fledged video cards (dedicated/discrete) are separate components with their own v(ideo)Ram - super fast memory helping them store and display prepared data rapidly.

Integrated cards are small chips soldered onto a PCB - they do not have their own memory as they were intended for very light work. They will use your system memory - much slower and used by all processes in your PC.

It seems to be running quite well at the moment but i haven't really tried to push it.

If you mean that you managed to run UE4 on that, then colour me completely and utterly impressed :D

Yea i guess your right i didn't give that too much thought. So again im being a noob but you said mine only supports up to directx 10.1, where are you able to find that info so i can look it up for future reference with other pcs? I knew the part about integrated vs dedicated i just didn't understand your terminology and i forgot that some (or all?) video cards do have their own memory but its good to have it in a clearer perspective thanks for that. Plus that will be great for anyone that reads this in the future.

Trust me i'm impressed to. I figured not to get my hopes up but not only did i get it to run but i was building onto the first person template a little and testing things out. I was able to run it on medium quality with resolution scale at 25%. From time to time i have to drop it to low but it pushing through somehow. Having my flashdrive with ready boost seems to help but maybe thats just my imagination. As long as i build everything like geometry and lighting seperately and dont just hit the build button it works but i hit the build button once and that was a mess. Had to force the pc to shut down.

I just googled it: https://www.notebookcheck.net/ATI-Radeon-HD-4200.20493.0.html

To expand a bit on the DirectX 11 - you'll be able to use some of the features of the API with a card that does not support it fully - but there will be next to no tangible benefits. No extra performance that DX11 brought.

Having my flashdrive with ready boost seems to help but maybe thats just my imagination.

I would not be surprised. Even if it's plugged into a USB 2.0, a half decent USB stick will be faster than the laptop's 5400rpm drive.

Well done, sir. It might be just enough to allow you to mess about with the editor.

Consider marking this as answered - the questions about what are the real min requirements of the editor are a bit of a mystery. Perhaps it will help someone find find their answer quicker.

Yea there's quirks here and there but i'm learning how to work around them so that's a plus

Done and done thank you so much for your help.
