Rockstar has said that it was 'aware of issues with slow download times for the day 1 patch on GTAV for PC and we are looking into a fix now.' Guide To Max Out the Framerate Redditor RUFiO006 has given us a guide on how to maximise the framerate in GTA 5 PC.
I think I managed to fix the error that the game never actually finishes downloading and every time you restart your internet/pc or it crashes or whatever, you lose a large % or some % of the download.
I was reading through one of the topics on here and it seems like the case was that the downloader was continuously downloading the same file over and over again but under a different file name (for example x64t.rpf 1.79GB becomes x64l.rpf 1.79 etc.)
So while you are downloading and using up your internet and hdd space, it's literally downloading the same file over and over again. Now, when you restart the downloader/it crashes, it sees this error and deletes the duplicated files, however, it still glitches up and downloads the same file again and again regardless, so no matter what you're in an infinite loop.
If you're having this issue, go to your GTA directory, and check the file sizes of each of the .RPF files and see if some of them are duplicated (x64t.rpf 1.79GB, x64l.rpf 1.79GB etc.), If there are duplicates, delete all the files that have the same file size and any remaining .rpf.hash and .rpf.part files in that directory. Afterwards, restart your launcher and it should start downloading correctly afterwards.
Down below is a list of all the correct .RPF file sizes. Remember to delete all the files with the duplicated file size, even if it's under the correct name down below because that's the one that's causing the issue and causing the other files to duplicate. Don't forget to delete the .rpf.hash and .rpf.part files too.

Edit/Update
I originally got the list of correct file sizes from a torrent site, which is why they're not the exact size down to the KB, the file sizes are just rounded to the nearest GB/MB, you can check via file properties on Windows. Another reason why some people are saying it's different is because they're trying to calculate it as 2,000,000KB as 2GB, when in reality that's not the case.
I've just completed downloading and it seems to have worked perfectly and is now giving me the countdown timer. I will be posting my MD5 checksum's down below alongside all my .rpf file sizes and a the total size of my GTA 5 folder.

------------------------------------------------------------------------------------------------------------------------Slow download speed/connection lost issues
Another issue people are having is slow download speed or connection lost errors. There's a fix online that tells you to delete the .rpf.hash/.rpf.part files. DO NOT DO THAT.
If you delete those 2 files without deleting the main .rpf file (x64q.rpf - x64q.rpf.hash etc.), you're telling the launcher to completely skip that .rpf file. The game downloads in chunks, which is what the .rpf files are. When the game finishes downloading one of the .rpf files, it'll start the next one, you will see the entire file size on your HDD, however, it's not there yet and not completed, it's just there as a placeholder to save that chunk of HDD space for that specific .rpf file. So if you just keep skipping, you' have the '60'GB of data, but they're not really there, what you really have is 60GB of placeholder data.
There is no fix for slow downloads/connection lost, it's just the servers, you have to babysit the download. Although it seems the download only slows down at certain times, in my case, mainly around the time one of the .rpf files are close to finishing the download. The connection lost issue also seems to only happen at the start of a new .rpf file, which is also around the same time you get your full download speed back. This is in my case anyways, I'm not sure if it's the same with you, but maybe it also depends on how many people are downloading and where you and the server you're downloading from are located in the world. In my case, I'm located in Australia and seem to be downloading from a server within Australia as well as my download speeds in most cases match those I get from Steam.

Edit/Update v2
If you've deleted the .rpf.hash/rpf.part files ONCE to move it along, it might be ok, since you'll proceed to download the actual file later along the download. This warning is mostly because some people were literally just removing every single .rpf.hash/rpf.part file every time it pops up and thinking they have the full 60GB.
tl;dr use an MD5 checker (Google it) to check every single .rpf file and see if they match mine up above/someone elses MD5 down below in the comment section
So I've got Gta V and while playing textures are blury or they don't even load (usually when I'm going fast) the other problem is that my game freezes or it just randomly drop fps

This has to do with the amount of GDDR5 RAM in your gpu most of the time.I had the same problem in mirrors edge: Catalyst and Fallout4. but is fixed now that i have a gtx 1060.
would you mind telling us your system specs since that makes it easier to pinpoint the cause of your problem.

If you're going really fast in a vehicle; textures tend to load very slowly if you are running an old SSD. RAM can also come into play, but 8GB is fine for GTA 5.

Perhaps try lowering your graphics, to reduce FPS drop. Some graphics settings are really intensive, so this might be a problem too. If you would like to change your graphics settings, press Escape (Or start on a controller) and Go to settings: Goto graphics, and then look at the video memory, Experiment with getting it as low as possible, while still pretty high, so the graphics aren't basically Roblox or Unturned :)
Gta V Update Slow Download
Uninstall your graphics driver and reinstall it and it should fix your issues. From what im hearing, it sounds like a graphics driver problem. Someone went wrong with the download, so id reinstall it again. Also, make sure you update your graphics driver, every time a new version comes out, that will help with games over all. Server could be issue also, it happens on consoles too, and it recently stopped. So either reinstall or wait for it to be fixed.
The thing that helped me when I had this issue was updating my Nvidia drivers. Sometimes I even had to downgrade the drivers because the new ones weren't optimized, but now the new ones are perfect. Also, if you are using the self radio feature, I'd recommend disabling it as this can cause slow loading of textures as well.

All these graphics stuff, is important, BUT I had a LAN party last time, and there it came up date my and my friends had popping up textures/slow loading textures on the same places. So it might be also a server-side issue.
