Some runners are saying PC Version lags for them. I want to know if we could get to the bottom of this... so I thought I would create a specifications listing thread. If there really is a problem with a specific piece of equipment that is causing game lag... maybe here we can see exactly what.

So, here are mine:

OS: Windows 7
CPU: Intel Pentium B970 @ 2.30ghz - Dual-core
Installed RAM: 6GB
GPU: Intel Graphics Family HD

Heard it's AMD that specifically causes these lag issues. Let's find out once and for all.


Windows 7
Intel i5 3210m 2.5ghz
4gb RAM
Intel HD 4000 graphics


windows 7 home edition
CPU: AMD FX - 8350 - 8 core
GPU: R9 270x amd radeon
16 gb ram

Had 3 different AMD systems and the game has always been fine for me

Edit; there was one time i had lag and i fixed it by switching compatibility mode from Xp Service pack 3 to service pack 2.


Windows 8.1 Pro 64 bit
CPU: AMD FX 8320 3.50 GHz

I barely run RE3 mainly because I still use the scrub Sourcenext version (I know right?) and I'm clueless about making Mediakite work as intended on my PC. There's a step-by-step installation guide somewhere?


Yeah I think stevenmayte has one on his youtube.

Windows 7 64 bit
AMD FX8350 (4GHz 8 core)
EVGA GeForce GTX 970

I haven't really tried running the PC version seriously, and I don't know how to optimize door skips so I would be a terrible person to ask about AMD.


@zenix i have a tutorial for mediakite in the guide section of re3

Edit; apparently someone decided to remove my guide from the guides section.

I have no lag on my RE3 whatsoever, I run it in SP3 compatibility, and also added and disabled that motor option thingy, it's smooth as anything.


I'm just not fully clear on what people mean by 'lag' though.

If it's actual game lag, as in, the game itself running choppy... which even mine sometimes does on Intel if I'm running a bunch of programs, or something decides to interrupt mid-run and spike my CPU.

Or if they mean it in terms of transitions / door skips.

Just thought I'd make this purely because a lot of the time when people say their game is lagging, I honestly can't see it on their stream. Not unless it's dropped to a ridiculous FPS and the camera transitions / load transitions are visibly a lot slower. A lot of the time people are just losing time and not understanding why because they're messing up the door skips which could make it seem like lag I suppose...?

I know I could not hit sub 46, even on a clean run, until I closed the SRT and took my time with each door skip to get them perfect. Then the next run I hit 46:00... then 45:39.


My computer is really weak, but there are my specs:

Windows 7 64 bit
Intel Core i5-3740 (3.20GHz 4 core)
NVIDIA GeForce GT 630

I have lags when game has a lot of effects. Someone can help me how I can fix it? Game generate strange "shadows". Look at this:


^ @Robercigg Go to the game launch file > Properties > Compatibility Mode XP (SP3)

Load the game up, then press F2 and go to the Video tab.

There should be a list of GPU options in a drop-down box, choose the one that ISN'T "RGB Emulation". Click OK, then close and re-open the game, those shadows should be gone and the lag should be too.

If you still experience glitches, try XP Service Pack 2, some people say SP3 still glitches occasionally for them however on SP3 I have experienced zero issues.

Trust me, your PC is a lot stronger than mine and should be able to run the game flawlessly.

i guess doorskipping would seem like lag for the doors that aren't instant skip and it explains where lost time is going, same thing with re2. i see a lot of re3 & 2 streams where people instant skip every door and wonder why sometimes it fades to black and other times it doesn't. i know i had no clue when i started out running, and i'm sure i sometimes skip wrongly even now.


I'm so stupid! Now works fine, thanks furrywulfz! ❤️


I'm gonna just post a guide for it, honestly. Would probably help a few people out.

Well I was going to ask the same as Robercigg, that RGB emulation thing was destroying the fps so ty Furry. Now the game runs perfect and I can finally uninstall the shitty Sourcenext.


Right so we have several people with AMD CPUs with which the game runs as normal. So we can at least rule AMD out partially... it's not a run killer.

Now the question is... is it AMD GPUs causing the issues?

(Seriously though if you see you're losing time and cannot figure out why, try two things:

1. Close the SRT if you have it up. I noticed whenever I ran the game with the SRT up the FPS would stutter in short intervals for maybe 3-5 seconds and then go back to normal.

It could just be my awful Dual-core CPU, but that alone proves that the SRT affects the game performance. Or that issue would not have ceased when I stopped using it. My CPU was not spiking or peaking during these times.

2. Try keep a mental note of door skips. Before I actually just took my time and paid attention to which door skips were instant and which weren't my time was suffering a lot. Watching a few runners that do complain it lags... and guess what? They don't doorskip right, or at least optimally. Which is why I connected the dots to maybe this conclusion.)


my GPU is AMD currently and so were my past 2 GPU'S > no issues for me at least

Current > AMD Radeon R9 270X
can't remember what the other 2 were

Edit; i also had the same issue as you furry on my old dual core. i couldn't stream the game and have the SRT open due to lag spikes but it was fine with the SRT closed.


There's a similar issue Shunpuk found a while ago in Silent Hill 3 on PC, performance issues that came up in modern machines that could be fixed with a few steps in Task Manager.

Whilst it was a very slight performance issue in the overall scheme of a run it affected things a lot. Fortunately for Silent Hill 3... the timer runs based off of frames and loading times are not counted so it's almost unnoticeable in terms of the IGT. However, RE3's timers is essentially an RTA... so if there is a similar reason behind the issues then it will affect the final time.

The Pastebin is here:

This is what Shunpuk recommended for SH3 everytime you launch it:

- Open up Windows Task Manager
- Go to processes
- Find "sh3.exe"
- Right-click, select 'Set Affinity...'
- Untick all options except 'CPU 0', and click OK

and if you are also streaming:

- Carry out the previous steps
- Now find OBS/Xsplit etc. in task manager
- Set affinity and untick CPU 0, click OK
- Make sure Multithreaded optimizations is turned on in your corresponding streaming application

That could be zero help in terms of RE3 on PC, however, it is worth a try.

I used to have major lag in RE3 and the options i had to choose from ingame was RGB Emulation, GTX 970, GTX 970 and GTX 970. non of the options didnt help and the extra options were all disabled.

They way i fixed it was going into my GPU controlpanel and create a specific profile for RE3 and then set all the options to "Best Performance". Some of the options had to be set to "Best Quality" cause there were some graphical artifacts in the game other wise.

So if you've tried everything else then try to setup a specific profile in your GPU controlpanel.


^ Do you mind writing a step-by-step guide for doing that?

Just that exact issue might be causing some players to be unable to play Mediakite, I mean there were two people already in this thread alone. 😕


I could do a little guide for it tomorrow for Nvidia. Dont know about AMD but it should almost be the same as the Nvidia controlpanel.

Need to install the Mediakite version and hope that I get lag on the first try otherwise I'll try to create it. I never thought that I would actually try to cause issues to the game, always been the other way around. lol
