Games won't run unless i disable one of my graphic card.

[reishenn1]

So, i have 2 graphic card on my laptop Acer Aspire 4830TG. which is Intel(R) HD Graphics 3000 and NVDIA GeForce GT 540M. when i try to run games it will say that they are unable to detect a graphics card. then i try to disable one of them from device manager > display adapters. when i disable the NVDIA, the game runs but with very poor graphic, and pixelated. then when i try disabling the Intel graphics, the game runs but with very poor fps. then i tried it again without disabling neither of them, and the games went back to saying no graphics card detected. any suggestion?

What games are you trying to run? It seems like you're getting poor fps because the NVIDIA graphics chip you're using is old, and the intel HD graphics aren't any better

Unfortunately the GPUs in your laptop (iGPU and gt 540M) weren't great when they launched and are whoa-fully inept for gaming save maybe some indie/esports titles. What games are you trying to play?

i'm trying to play Terraria, Don't starve, and digimon master online. but Dota 2 works fine for no apparent reason. this starts to happen after i installed .net 4.7

Well you could start by uninstalling the .net 4.7 and see if it fixes things. If you must use it for a game/program you could try a reinstall in case something went wrong with the original install.

.net 4.7 is not a program i can uninstall

No need to disable anything. If you right click on the screen and select nVidia control panel, select Manage 3D settings, it should read thet the default GFX processor is "auto select". On the tab to the right (Program Settings) you can assign any *.exe file to use the GFX Processor of your choosing. Bth are so old that test results have been archived and you have to dig a bit to get test results

At 1024 x 768, the 540m delivers 36 fps in BF3 ... the HD3000 just 11 fps Full comparison here:

As for the ,net stuff .... my guess is that it is not the problem ... and some hardware driver that came down in the same Windows Update is what nerfed things up.

If you need .net 4.7 you can reinstall it after uninstalling it. To uninstall it, right click the windows start menu. Choose search. Type in control panel. Choose add remove programs. remove any microsoft .net program starting with the newest to oldest. to reinstall .net go to
