Re: The Sims Medieval Graphic Issues (2021)

@SuperDrivin Alright, so the files you will need to update, GraphicsRules.sgr and GraphicsCards.sgr, are located in C:\Program Files (x86)\Origin Games\The Sims Medieval\Game\Bin\ if you have the Origin version of the game installed in the default location. I recommend making a backup and also moving them to desktop for editing in case it doesn't let you save changes in the installation folder. You can use Notepad to edit them.

Once you open GraphicsCards.sgr, look for the line vendor "NVIDIA" 0x10b4 0x12d2 0x10de.

Under it, add this: card 0x2191 "NVIDIA GeForce GTX 1660 Ti" so it matches other entries, then save the changes. Move the file back to the Bin folder.

Open GraphicsRules.sgr and, near the top, find the line seti textureMemory 32. Change 32 to 1024. Under it, add # before setb textureMemorySizeOK false so it looks like  # setb textureMemorySizeOK false. 

Then, search for GTS 4??, there should only be one entry for the Uber section under NVIDIA. Replace it with GTX 16?? and make sure that quotation marks, asterisks and brackets remain untouched. The line should then look like or match("${cardName}", "*GTX 16??*")) once you've made the changes. Save and move it back to the Bin folder.

Once you've done that, launch the game, wait until the main menu loads, and close it. Check your DeviceConfig.log, and the Name (database) should list your card's name and say Found: 1, Matched: 1.

To cap the frame rate and enable vertical sync, open NVIDIA Control Panel > Manage 3D Settings > Program Settings, and find The Sims Medieval (tsm.exe) on the list. For settings, look for:

• Max Frame Rate: set it to 60 or whatever your screen refresh rate it.
• Triple buffering and Vertical sync: turn them both on.

Save the changes, and remove the frame rate mod that you mentioned before as it's not needed. Launch the game and see if anything has changed. I would recommend testing a clean user folder without mods just to check if there's anything else that might be causing it.

@mate54 I did as you said and the graphic glitches are still there (I've attached to this answer a picture). I doubled checked your instructions just to be sure that I hadn't skipped anything (which I haven't) and the only problem that I've encountered was the fact that in DeviceConfig.log the graphic card that I've added was found but not matched (I've also deleted the Electronic Arts folder in Documents in order to create a brand new one, but nothing changed).

One thing that changed was in the options of the game. I get the message about my video card not being recognized, but in the graphic options some setting were higher than normal from default (like the Shadows and the Sim Quality). But other than that I've noticed from the start some other minor glitches (for example: if I followed my Hero the camera started to shake a little bit everytime it moved to follow it, also the screen became brighter all of a sudden). I've also changed the setting in the NVIDIA Control Pannel as you said and I've removed the Mods.

I think I'm just cursed with EA Games (cause I'm also experiencing some crashes with The Sims 4, but I don't have the patience right now to deal with them). I just wish I could get a refund and get over with this crap. -_-
