Hiya @elishacloud , Thanks to @Durfsurn 's kind sharing, I started to try dxwrapper as well, but have no luck in running SC4 with dedicated card, here is my tests's result: https://community.simtropolis.com/forums/topic/759351-raymonds-newbie-thoughts/?do=findComment&comment=1737944 I have no idea if there is any chance among the settings, Appreciate any tips on this, i can do any further tests if it's necessary, Thank you for your selfless efforts. at least you bring light of hope to our beloved game. Thanks a million! Sincerely, -- Raymond

Hello @rainman7cn, yes, the Dd7to9 does not yet support 3D (hardware driver) functions. I am working on adding them but they are not there yet. You will still need to use the integrated video card and not the 3D accelerated one. However, with this project you can use 4k resolution.

Here are the only options you want enabled:

DDrawCompat         = 1
DdrawResolutionHack = 1
EnableDdrawWrapper  = 1

Then you can run the game with a custom parameter to get the higher resolution. Command line option is:

"SimCity 4.exe" -CustomResolution:enabled -r3840x2160x32

Just change -r3840x2160x32 to the resolution you want. Keep the x32 at the end. That tells the game to use 32bit color.

Thank you so much Dear @elishacloud , I see, and you are doing something greatest, we all appreciate the efforts you put into this, Please allow me to follow your work, it's my honor to be here to witness this historic moment. Sincerely, -- Raymond
