FiveM stuttering or FPS drops? Check your PC first
Check the PC before you change Windows settings. Games often stutter because the PC is not set up right yet. Everything on this page is what the Home page of Savenz Optimizer checks when it opens.
1. An old graphics driver
A driver that is months old can make new games stutter or crash. Get the newest one from NVIDIA, AMD or Intel and do a clean install.
2. One RAM stick, or sticks of different sizes
One stick, or two sticks of different sizes, runs in single channel. CPU heavy games like FiveM lose a lot of FPS. Use two sticks of the same size in the slots your motherboard manual names.
3. XMP / EXPO is off
Most RAM runs slower than the speed you paid for until XMP (Intel) or EXPO (AMD) is turned on in the BIOS. Compare the MT/s it runs at with what it supports.
If games crash or you get blue screens after turning it on, turn it off again. Unstable RAM can damage files downloaded from servers.
4. The graphics card is missing lanes
A card in the wrong slot may get x8 or x4 instead of x16 and lose FPS. Move it to the top long slot of the motherboard.
5. FiveM is on a hard disk
Move FiveM and GTA V to an SSD. Loading gets much faster and the city keeps up when you drive fast. Keep at least 20 GB free for FiveM's cache.
6. Overlays and recording tools
Programs that draw over games, such as Discord, Steam, NVIDIA and RivaTuner, can make games stutter or crash. Turn off their in game overlay. If you record with OBS, use Display Capture instead of Game Capture.
7. The paging file is off
Many tweaks turn the paging file off. FiveM needs it: without it the game runs out of memory and crashes, even with 16 to 32 GB of RAM. Set it back to System managed and restart the PC.
8. FiveM's cache is broken
Files downloaded from servers (cars, maps, clothes) can get damaged. Clear the FiveM cache and join again. If it only happens on one server, tell that server's staff.
9. Risky values left by other tweak packs
Some .bat or .reg files change values that make the PC worse and have no way back. Savenz Optimizer counts them and puts the Windows values back on the Safety repair page.
10. Win32 Priority and Timer Resolution
There is no single best value for every PC. Test both on your own PC on the Win32 Priority and Timer Resolution pages of Savenz Optimizer.
Measure it
Don't go by feel. Measure average FPS, 1% low and stutters before and after a fix. Result Card in Savenz Optimizer measures with Intel PresentMon and counts a frame that takes twice as long as usual and 25 ms or more as one stutter. Anything that gets worse shows up too.
