So is there any real reason why the leaderboards separate each console? If it's IGT technically each should be equal right? Has anyone actually tested this or is it more separated as a rule of thumb

Just due to the fact there are only 3 different versions. Helps people watch a video of their own platform.

Why is the level leaderboard not separated in that case? It seems the board could just have them all together since it's not really different

I have played the PS3 version and have seen a few videos of the PC version and I believe to have observed the following differences (as far as I know, PS3 version received a patch that the PC Version didn't):

• On PC version, you can use melee as much as you want. On PS3, you get a cooldown after using melee twice in a row (it can be bypassed though. If you don't plan to transition into a brutal kill animation, you can cancel the recovery animation by holding the shooting button. If you hold the shooting button and time pressing the melee button correctly, you can not only melee as much as you want on PS3 as well, but also melee faster in general.).
• On PC version, you can dash as much as you want. On the PS3 version, however, the dash drains all your stamina and takes away the ability to sprint or dash for about 2 or 3 seconds.
• On PS3 version, it is possible to use the dodge to jump into cover. The dodge animation can therefore be canceled preliminary by touching anything that supports cover. I haven't seen this being possible on the PC version. Therefore, the PS3 version enables another trick. The dodge jump seems to instantly refills your stamina because if you jump into cover every now and then while sprinting, you can sprint forever.

I cannot tell to what degree these three aspects can affect speedruns. I also don't know anything about XBOX 360 because I hardly find videos of this version.

I've also noticed that the Xbox 360 version has several advantages over PC, mainly because PC is prone to crashes very often

When doing side-by-side comparisons in order to identify points for optimization, and due to the lack of competition in this game overall and especially on the PS3 version, I used runs from different platforms for comparison. This is where I noticed that the IGT on the three platforms does not represent equal performance. After comparing the video intervall between the opening CGI of a stage and the result screen with the in-game-time (assuming cutscenes are skipped immediately and the game was not paused) for multiple runs on each platform (only the recent ones that show the in-game-time could be used though), it appears that while the IGT of the PC version is accurate, the one of the XBOX 360 version is delayed by about 3 seconds and the one of the PS3 version by about 12 seconds. So far, the mentioned numbers are only estimations. The accuracy of the PC version and the delays of the PS3 appear to be stable though. No statement can be made about the XBOX 360 version because only one run exists that shows the in-game-time.

In summary, the IGT's don't show equal performance and the consoles have a delayed IGT, so a distinction between platforms for full runs is not optional. IL runs are only reserved for PC versions since XBOX 360 versions cannot compete on heavily optimized IL's while PS3 versions cannot compete at all and have to consider full runs instead. (All information provided here refer to the 'Solo' category)

It makes a lot of sense. I was always surprised on how runs on ps3 or x360 were so slow compared to my pb (53:58, not submitted), even though my runs are bad, and died multiple times.

I wish I could make a livesplit plugin for this, I'm really interested on some possible skips/timesaves regarding igt.

The fps makes a big difference for igt, that's why they are separate.

@rozukk I guess you refer to the many deaths you had in the final encounter on chapter 7. I don't know any details, but I have noticed that dying once or multiple times during this encounter does something to the IGT that keeps it much lower than it is supposed to. I have seen this on a Let's Play where someone tried to defeat Leon for about 50 minutes and died 8 times until giving up and going for defend instead, but ended up with an IGT of 19:11. I have no idea when, how and why that happens (and if it is restricted to console versions before receiving the patch and the PC version), but this odd occurence is the reason why your mistakes on the final encounter didn't have severre consequences on the time and you still got a good 04:25.

I'm gonna guess that the timer stops as soon as you die, and keeps on going as soon as you gain control. Cinematic cutscenes like end of the line's choice don't move the timer as well, which could mean that my 4:25 was because of a 15/20 second timeloss per death. Environment cutscenes (like ep6's beginning cutscene, or Nicholai's speech at the start of ep3) seem to move the timer though.

It was a little hard to find something about the history of this game, but according to some findings, PS3 received the patch 1.03 that made major changes to the gameplay (I have checked my PS3 game and can confirm that it runs on 1.03). I couldn't find a source stating what version XBOX 360 is on, but due to observing similar bahaviour to the PS3 version, my guess is that it runs on 1.03 as well, but I don't know. The version most different is the PC version and has a complete different version number. It seems to run on 1.2.1803.132 or 1.2.1803.135. Despite 1.2 being a much higher number than 1.03, I didn't observe any of the 1.03 changes of PS3 being in the 1.2 . So I believe the cause of currently discovered differences between PC and PS3 (and 360 ?) and potential future discoveries of differences are these two different version numbers.
