i had the same problem and thw thing that helped me the most was getting timer resolution and setting it to max 0.5 this should help you average at 80-100 fps in BR

also, delete crash files on %localappdata%>fortnitegame>saved>config>crashreportclient (from: https://www.youtube.com/watch?v=bC89XChu8o4 @1min)
then delete everything in crashes, logs, webcache, demos (replays) (back it up if you want to: just copy those files to another folder)

you should try DirectX 12 in the graphics settings
and turn these off in the UI settings:
contextual tips OFF
quest progress OFF
and turn off replays, nvidia highlights, etc. in the settings as well
also enable multithreading

oh and high textures is better on high end graphics cards because it lightens the load on your CPU (very important for more FPS and better perceived smoothness) – apparently low/medium is rendered on your CPU but High and Epic are rendered on your GPU – you should try High and Epic and see which is better for your setup

limiting fps will also lower CPU usage since it lightens the load on your CPU (your CPU has to do more work for each frame that is produced) – this is also very important for perceived smoothness i.e. “fps” (probably improved input lag/visual from the freshness of the frames)
also jump fatigue and other stuff is affected by fps limit because bad coding
also, for some reason you should limit it to [monitorHz – 3] – e.g. 144->141; 240->237 – because for some reason it makes the game run even better than just matching your refresh rate – you can limit it in GameUserSettings (C:\Users\\AppData\Local\FortniteGame\Saved\Config\WindowsClient)

also, you should really research what to change in GameUserSettings, there’s a million things to do here for performance boosting,
including:
change the DisplayGamma to 1.000000 (apparently actually affects the smoothness of the game)
bShowGrass to False
bDisableMouseAcceleration=True
sg.FoliageQuality=0
sg.ShadingQuality=0

RadeonBoost is literally game-changing
you should REALLY consider using RadeonBoost or nvidia equivalent on minimum possible number (dynamically adjusts resolution when you move the camera, GREATLY improving the perceived smoothness (“fps”) of the game without losing >any< graphical fidelity)

don't use the -NOTEXTURESTREAMING launch option, it seems to make my character move slower (???) like much slower acceleration to top movement speed

don't use radeon anti-lag or nvidia equivalent either (try it on and off and see why – to me it adds input lag, A LOT of it)

also, you should try different values for maximum pre-rendered frames (default is 3) – I like 3 better than 2, but I haven't tried 1 (nor 0)

disabling Windows Libraries is ultra important (e.g. Videos, Images, etc.) – they're just a collection of folders, you can just right click and disable each of them – huge enormous reduction in input lag
removing everything from your desktop is also extremely important, as is clearing your start menu, and even having files inside your recycling bin – another enormous reduction in input lag (especially desktop and start menu for Windows 7 – no clue about start menu in Windows 10)
also, delete/move everything from the downloads folder (what even is windows, why would this matter???? but it really does)

SET TIMER RESOLUTION TO 0.5 (quite big increase in perceived smoothness of the game) – https://www.youtube.com/watch?v=EG4g9XlKw5w
timer resolution is extremely awesome, you can use ISLC and force it to 0.5ms (requires below stuff otherwise it won't stay at 0.5ms) – just remember to open the program every time before starting the game (it doesn't seem to auto-start with windows even though it shows the icon on the taskbar – probably something to do with requiring admin permission just to open the program)

also random cmd stuff that has to do with timer resolution and other stuff (still great even if you don't install a timer resolution program, but installing one will make a huge difference too)
cmd.exe (as admin):
bcdedit /deletevalue useplatformclock (do not use: bcdedit /set useplatformclock no)
bcdedit /set useplatformtick yes (disables windows 10 synthetic timer) (windows 10 only)
bcdedit /set disabledynamictick yes (power saving feature for laptops) (windows 10 only)

registry stuff REALLY matters a lot, A LOT – huge boost in fps, smoothness, input lag, etc.
especially SystemResponsiveness set to 0 (or 1 if bad PC)
there are many videos on this, just look it up on youtube – "fortnite registry optimizations adamx"
also forcing fortnite to run at high priority is extremely good too
and the GPU stuff is also extremely good too (but SFIO changes the way your mouse feels, for me Normal is way better than High – try both and see which you like the most)
if you download random registry files from youtube videos, you can right click the .reg files and edit them with notepad++ or some other advanced text editor. It's gonna be just a couple of lines of text:
(Priority)
A .reg file that sets Fortnite to High priority should look like this:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\FortniteClient-Win64-Shipping.exe\PerfOptions]
"CpuPriorityClass"=dword:00000003

(^AboveNormalPriority (lower than High) is 00000006 (yes that number is higher, just registry things))
(NormalPriority is 000000002 if you want to change it back, but try …0006 first)

(GPU)
The GPU optimizations should look like this:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games]
"GPU Priority"=dword:00000008
"Priority"=dword:00000006
"Scheduling Category"="High"
"SFIO Priority"="High"

(but remember to change the SFIO line to "Normal" or just delete it from the file)
(I don't know which of these settings made the biggest impact since I haven't tried each of them individually. I prob should do this later since SFIO made such a huge (negative) difference – I don't know if these are all positive.)

and CPU optimizations should look like this:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile]
"SystemResponsiveness"=dword:00000000

(^this should be set to 00000001 if your PC sucks, try both if you want to be sure – this is how much % of your system is reserved to "under-the-hood" stuff, the default is 20(!) which makes this basically the same as upgrading your CPU by 20%)
)

change your sensitivity to under 10% and then raise your DPI accordingly
e.g. if your sens was 32.0% @400DPI, change it to 8.0% @1600DPI
this will reduce/completely remove pixel skipping, which will make your game show more frames while moving the camera around, improving your ability to see clearly during camera motion, I'm not sure what the exact number is where pixel skipping begins, but it's around 10-15% – you should set your sens to a number under 10% just to be sure, just keep in mind that some mouse sensors perform worse at very high DPI values, so it might not be worth the sacrifice just for a little bit of camera smoothness

you should also install Fortnite on your SSD if you have an (internal) one, not an external USB one though

disable drive indexing and compression (video: https://www.youtube.com/watch?v=bC89XChu8o4 @2:29)
video-maker: "this will boost fps a lot!"
I don't know the actual effect of this since I already did this a very long time ago

also, it's good to defrag your hard drive once in a while if you do this, just please don't defrag your SSD if you have one

optional – win+r: msconfig
then disable everything you don't need (you probably have a lot of garbage there both in Services and in Startup)

you can also also uninstall whatever programs you have installed but don't use, I don't know what the effect of this is, if any

that was a lot of stuff, you better add it to the guide or I'll slap you
it took me half a decade just to write all of it down

Hey Kaleb, what are your computer specs/settings that you played on before and after settings

The GT 730 is THE the problem. Try a cheap second-hand HD 7950 3GB or a HD 7970 3GB and be sure your power supply unit has enough juice (450W, 80% efficiency for games). It will work wonderful with your Ryzen 5 CPU. Used one of these with a i5 2400 and 100 FPS with all settings on Epic was what I got, beautiful playing experience, no lag, no video problems at all, saw all players on the entire map from a long distance. A good motherboard is also required. We all know that not all motherboards are born equal. 8GB RAM is also enough. I never needed more RAM (still using DDR3 and didn’t have an issue in any of the games I am playing)

It might be that your cpu is being bottle necked by your gpu

hey i had like 38fps now a nice (160+)thank you so much

I would always recommend to build your own pc. I don’t necessarily mean that you have to physically build it yourself but being able to pick the parts will mean you will get a lot more for your money. I’m not sure where you are based but something like pcspecialist or scan allow you to pick your parts and they build it for you if you aren’t comfortable getting the parts yourself.

For Fortnite all you really need is an i5 and a decent graphics card. Maybe something like a GTX 10 series will get you by for now. Or if you are on a budget have a look at AMD as they do some equally great products at a cheaper price. It really depends on what you need and what you will be using the machine for.
