Dear laquintin,in this case I suggest you try to perform a clean installation of the NVIDIA drivers;
Download and run the latest driver package for your video card:https://www.nvidia.com/Download/driverResults.a...
Follow the onscreen instructions until you get the Installation Options window;
Select the Custom (Advanced) box and press Next;
On the next screen, you will be able to choose the components to install (all should be checked by default and if you're not sure, leave them that way);
In the Select driver component table, check the Perform a clean installation box and click Next;
Before restarting, run a disk cleanup;
Press Windows key + R and type: cleanmgr press Enter;
Click on clean system files and wait for the files to load;
Select all files and click ok to delete them;
Restart the PC;
Try verifying the integrity of the files on Steam;
Open Steam and access Library;
Right click on GTA5 and go to Properties;
Click Local Files;
Click Check the integrity of files...;
Try starting the game again and check the behavior;
Hope this helps, see you soon!
