max amount of polys are 250k with sometime exceptions by 25k Step 1:
Download OpenIV: https://www.gta5-mods.com/tools/openiv and follow the installation instructions. You need to verify your GTA V folder.
You will also need a zip extractor. I suggest winrar
Step 2:
Open OpenIV and select Windows
Step 3:
The program will open and look like this:
After it opens, select the mods folder, and then enable editing by clicking "Edit Mode" at the top.
Step 4:
Now that you have OpenIV ready, you need to find a car that you would want to test! The best website to find them is: https://www.gta5-mods.com/vehicles
Make sure that any vehicle you find is an addon vehicle. I can do replace vehicles, but I will not do them due to the hassle.
Step 5:
Now that you have the car, click the big green download button and complete the download. The file should open in winrar. For this example you will see addon, and replace. Click addon:
Continue to navigate through the add-on folder until you come across a dlc.rpf file.
Step 6:
Once you have the dlc.rpf file, you need to drag it to openIV (MAKE SURE YOU HAVE EDIT MODE ENABLED!)
Step 7:
In OpenIV, double click on the dlc.rpf file, you will then see "data and x64" in most cases.
The data folder is useless for testing cars in openIV - it has the actual car metas, such as handling, body kits etc. You will want to select the x64 folder.
Step 8:
In the x64 folder, you will see:
The file you want is the vehicles.rpf - this is where you can see poly count, LODs and texture file sizes. The vehiclemods folder in this example does not matter and is useless. If I were you guys, I would not worry about vehiclemods, as most cars have them, but do not come with any special body parts or extras.
Step 9:
Now this is where things get fun. Double click the _hi.yft to test the poly counts of the vehicle. See the image for explanations on rest.
Step 10:
