Low FPS with my new RX 5700 XT

[Amki45]

Hello,
So, I'm not quite new to modding and wanted to get another round on my favorite game. In my last build I was around 37fps avg with a GTX 970 and a whole ultra settings and 2K build (300+ mods).
And now with my new graphics card I think I could reach the 60fps gameplay. So I followed a modlist and made some adjustements (list here, demonstration here). I have done a 4k-2k build and I'm running at only 30fps... wtf, someone in the comments said "Tested in a GTX 950 with a Athlon x4 860k stock on 768p and working on 30fps" !?! (Random location on Solthsteim left to Miraak's temple, there is a wounded body of a woman)

I'm also using Rudy's ENB (3fps gain when I disable it... IMPRESSIVE).
Fresh Windows 10, fresh graphics drivers, bios updates...
I have done a perfect installation (no crashes so far): using MO2, setting loadorder with LOOT, remove ITM with SSEEdit, build LODs with DynDOLOD, run BodySlide...
I don't know if I missed something like a mod or a step...

My Specs:

 

FHD 60Hz LG Screen
Asus TUF RX 5700 XT (Yes I know about the memory problem but it's not causing my issue)
Intel i5 4690 @3.5GHz
Asus B-85-MG
12 Gb or DDR3 @1600MHz

Did I messed up or did I get too greedy ?
(If some of my installed mods are very fps-unfriendly I could test without them if it makes the difference)

[JimmyRJump]

I'm on an R7 2700X and a Vega 64 with 2x16GB of RAM and averaged 44.7fps in 1080p over a period of roughly 300hrs, according to the Radeon Adrenalin 2020 Software (v20.1.2 -later versions are screwy for me). I do have 700 mods installed with 360 plugins (253 regular, the rest 'light') with quite a lot of 2 and 4K texture improvements.

 

44.7 may seem low, but I have smooth gameplay with no visual stutterings or hamperings. Only 'problem' I have now is that RAM doesn't seem to flush properly and accumulates during play which results in having to restart the game every couple of hours, depending on how many times I change cells, because the game threatens to go over the 8GB V-RAM limit of the GPU.

 

I stopped caring about fps years ago, because, in the end, it doesn't matter as long as a game runs visibly without a glitch.

[Amki45]

Most of my textures mods are set on 2k I'm using 4k only for males and females bodies and only 1k for small things like eyes, mouth...
I would stop carrying for fps if I was at least above 40fps but that's not the case.

I upgraded because I wanted to play Skyrim with more fps and better graphics but I just can't.
30fps average in random locations is really low for my specs and it's not a VRAM issue cause I always run new save for testing and VRAM does not exceed 50% (4GB / 8GB).

Only 260mods, I downloaded everything I wanted but I'm very disappointed.

[JimmyRJump]

Well, 2K is four times larger than what the vanilla game has. You have to keep in mind that the game's engine is almost ten years old meanwhile. And you can be unhappy about average fps, but does the game run smooth? If it does, then who cares about low averages. I mean, you wouldn't know if you didn't have a look at the results. I didn't know I had 'only' 45 fps on average. And I don't feel bad now that I know, because, like I said, it's not noticable when I play.

 

For all I know, averages could be pulled down when having a black transition screen when you change cells or fast-travel. Then you would have bad fps results because of parts of the game where fps doesn't matter.

[Amki45]

Okay, so
Sorry to bring up this post, but I've some news and I hope it can inform and help people that are in the same situation as me.

I found the reason to the problem but currently there are no solutions.
The problem simply comes from the AMD drivers which are quite unstable lately and especially for users of the latest RX 5000 series.
Some of you may already be aware of crash issues with black screen (or green screen for those with older screens like mine). Personnaly I was getting them on Skyrim SE before the 20.2.2 update.

I found that if I enabled the "Radeon Chill" feature I would not lower my FPS to save power but instead to increase the minimum FPS to have a stable and playable game (sometimes it runs at 5fps in small interiors like farms). And it works ! Stable game, reasonable temperatures and FPS that doesn't go below the minimum limit that I've set.

The problem is that this feature causes the problem stated above, a green screen for me (even after 20.2.2 update).

So I think we just have to wait for AMD to fix those bugs. Hopefully it won't take very long.

[mistafresh]

A couple weeks ago, with the lockdown situation, I decided to get back into Skyrim. For that reason I was wondering whether or not to buy a new Radeon 5700 card in order to enjoy the best possible graphics with mods. I made a quick google search to get some feedback on its performance, and I stumbled upon this exact thread and it really made me wonder whether or not to go ahead or buy nvidia instead.

 

Nvidia has some great cards and technology, but in my opinion they have gotten too comfortable and need some competition if we want to see powerful and affordable cards in the future. So obviously I would not buy a defective AMD product over a working nvidia one, but all other things being equal I would go AMD in the current situation. I decided to go forward in spite of the negative reports and buy a Gigabyte Radeon 5700XT Gaming OC 8G. Anyway I can return it if it doesn't work.

 

After a few hours of gaming, this is my feedback:

 

- to have results that can be compared, I installed the Phoenix Flavour modlist with Skyrim Special Edition using Wabbajack and the Visceral ENB, and basically followed the exact recommendations described in the Phoenix Flavour modding guide. So anyone can easily follow the instructions there and get the same result that I am getting. By the way I recommend this guide if you want a stable, very beautiful Skyrim that also performs very well. It doesnt add too many mods so its a good starting point to make your own custom modded Skyrim, and with wabbajack it takes care of the boring parts of modding like downloading all the fixes and cleaning the masters for you. For this purpose I took the nexus 1 month subscription, and having a good internet, I got the modlist installed in a matter of minutes.

 

- I play at 1440p aka 2560*1440 resolution. If you play at 1080p, you can get a much cheaper card like an rx580. If you play at 4K, at the time of writing you will need a more expensive nvidia card like the 2080 or 2080ti.

 

- the Adrenalin 2020 Edition 20.2.2 Recommended (WHQL) drivers released on 5/3/2020 seems to have solved most stability and performance issues. I installed these drivers and I am getting butter smooth, stable gaming, with a beautifully modded Skyrim, at 1440p resolution.

 

Full disclosure : a few years ago I played Skyrim Legendary Edition, and I was getting fps in the low 30s with a 1080ti, because I had picked the most graphically intensive mods at the time. I had no idea which mods really made an improvement to the visual quality and just set everything to max and downloaded the highest resolution texture packs. But there is such a thing as diminishing returns, and unless you just want to be taking screenshots, its a real challenge to evaluate every mod you are adding and whether or not the performance impact is worth it, and I believe that will be a lot more important for your FPS than the brand and model of graphics card you get. As a noob and not having the time or inclination for hours of trial and error I can safely recommend the Phoenix Flavour modlist as they have done this curation job for us.

 

Conclusion: the driver issues plaguing the Radeon 5700 XT seem to have been worked out with the latest driver updates, the card works fine and to get better performance it is crucial to pick well optimized mods. Hope this helps another lurker.

[Amki45]

After further investigation,
It seems that after update 20.2.2 less than 10% of RX 5700 card users still have some problems with their cards.
Sorry if I have given an opinion which does not correspond to the globality and especially to the majority of the users, it was not intended. I was just wondering if I'm the only one who's encountered these kinds of problems and maybe found a solution. At the moment, I think that the only solution is to wait for AMD drivers updates and BIOS updates from custom graphics card manufacturers.

After 20.4.1 update, always observing the same problems for my part, there are also a few other games where I encounter similar problems, like TESO.
It would appear that this does not concern all places and all games and that it is not a performance issue. I can assure that because I recently tested another ModPack even bigger in therms of performance cost.
In some places and also according to what is done before (see if I load my backup directly in the zone) the GPU seems to react differently. Sometimes it behaves normally and allows me to get up to 60 fps (with no slutter, correct temperatures that prove that the gpu is working) and in other times the GPU seems to be lazy with low temperatures, fan speed, electric consumption (only the VRAM behave normally) that results into low fps (between 5 and 30 in most cases). Same situation in TESO.

I will update this topic when I find something interesting or if I come up with a solution.

For AMD make sure the settings are as below

Vsync in game = off --> use original launcher launch and tick off Vsync > close it.

Go to: Ducuments>My Games>Skyrim Special Edition --
now edit with Notepad both files to match as below if a line is not there add the line.

Skyrim.ini =
[Display]
iPresentInterval=1


Skyrimprefs.ini =
[Display]
bBorderless=1
bFull Screen=1
iVSyncPresentInterval=0
bBorderless=1
bFull Screen=1

and last whe are going to let ENB do Vsync so go to Skyrim folder same place as Skyrim.exe open enblocal an make sure it matches this:

[ENGINE]
ForceVSync=true
VSyncSkipNumFrames=0

[LIMITER]
EnableFPSLimit=false
FPSLimit=0.0


With Limiter you have a choice you can let AMD with chill lock the frames for 60 i would do min 59 max 61 or use ENB you would change 0 to 60 if not leave it at 0, so recap if you use ENB for Vsync leave at 0 or lock 60 , if you use AMD leave at 0 en set it in the driver software and speaking of it...

Now in AMD software go to the game profile

Enhanced Sync = Disable (should be off by default)
and also
Wait for Vertical Refresh = OFF.

That should unlock/fix it, you can lock to 60 or more but don't forget to adjust for over 60fps.

[mistafresh]

If you have an issue with your card, you can send it back. Or buy another card to see if it is better, then return the one that performs worse.

Someone asked me which ENB I was using.

The first days I used Visceral ENB and game settings at high. Great visuals and FPS at 59.9 which is the maximum you can get with the Phoenix modlist (it locks fps at 60). Could probably go much higher with such reasonable settings, but my monitor does not go above 75 Hz anyway.

 

Then I tried Re-engage ENB, high quality preset (the one just under ultimate) with game settings at ultra and with this configuration I'm at around 55fps. I have a freesync monitor so I enabled variable refresh rate, and as long as I'm above 50 fps, it feels smooth enough.

Although Visceral looks nice, Re-engage actually looks an order of magnitude better, so I'm willing to take the small FPS hit. I mean I thought Visceral looked great until I tried Re-engage... The same scene looks completely different.

I put the game settings at Ultra because when I use bows I want the maximum depth of view to spot ennemies from far.

Other than that, I'm using Ryzen 5 3600 with MSI Mortar Max motherboard and 16 GB of RAM.

This problem is something known in the game with AMD cards and the engines Vsync, if the Vsync does a nice drop it kinda off locks itself to the 30's no matter what, has nothing to do with a bad card or Driver issues if that's what you was thinking.

I had the same problem that's why I know took me about 5 months of digging around, matter of fact a way to test it is if he puts it in windows mode with borders and if your fps jumps up to where it should then you know the Vsync thing is the issue.
