I have found a POSSIBLE fix for 2gb cards

[Desmight]

DISCLAIMER: this fix is not guaranteed to work. It worked 100% on my rig, but may not work on yours. Since it is possible to restore everything to default if it doesn't work, I'd suggest to try it anyway, if you're experiencing huge and unexpected frame drops (from let's say a smooth 50-60 to 25-35 fps) on 2gb graphics cards (Nvidia OpenGL, mostly).

----

You know, there have been lots of issues with those cards and I think I've found a fix.
It's about modifying the config file of Doom in read-only mode, so be sure to tweak your advanced graphics settings (keep virtual paging at low) before trying it. The fix seems to work only in OpenGL mode (on Nvidia, things could be different on AMD).

- Open the local config file of Doom, it's located here: %USERPROFILE%\Saved Games\id Software\DOOM\base\

(Should be DOOMConfig.local and you can open it with the Notepad)

- Here, modify "vt_pageImageSizeUnique" and "vt_pageImageSizeVmtr" from 4096 (or whatever value) to 2048

(Try adding the lines, if they're not there)

- Save and put the file in read-only mode

This solved every episode of "fps-tanking" that I was experiencing. I don't know exactly what it does, but it's probably related to texture loading, texture streaming and texture pop-in. If it doesn't bother you and you're having issues on a 2gb card that's on par or exceeds the minimum requirements, you should try this method. The issue seems to be a vram-related thing, without the fix the game didn't use all of my vram (only 1600-1700 mb) and used at 99% my gpu, causing frame drops in the 30s and 40s (that were fixable only after a couple of restarts of the game). With the fix, it uses all of my vram (1950-2000 mb constantly) and gpu usage is ok. Now I have 45-60fps at 1080p, 50-60fps at 900p and 60fps locked at 720p, on high settings (GTX 760 OC).

To put everything back to default, just remove the read-only mode and launch the game (or restore everything manually).
Hope it helped (and sorry if my english is not outstanding) :)

Tried on my rig. I have a fx 6300 and a rx 460 2gb version with 8 gigs of RAM. The framerate in 1080p is much higher after i changed the number(maintaining in 70 fps), and it is pretty stable. I use vilkan, so seems like it works for vulkan in my case.However, I encoutered frame drop in some area(down to 45 fps). Other than that, I have no more complain. Btw I am running in medium with some tweak in the graphic setting.

[Curled Woofy]

I have a R9 270X on 1200/1590Mhz and will test this now. Another problem I have is that loading the main menu stops at 99% for about 5 minutes. Any solutions?

[Gusta]

I've tried tweaking my game with commands like these, but could get vt_pageImageSizeVmtr 2048 to work with Vulkan, it always freezes after loading, should work with OpenGL tho, but i'm looking towards Vulkan since the game runs smooth with it. With my 2GB RX 460 I managed to get some decent framerates, averaging 90fps in the entire campaign. Multiplayer maps are different story, most of them run at 60fps, but the newer, DLC maps RUN LIKE TOTAL ASSCRAP, Empyrean is good example of unoptimised map, 15 fps average, FIFTEEN ♥♥♥♥♥♥♥ FRAMES.

I will try to test these maps with OpenGL and vt_pageImageSizeVmtr 2048, the results above are with Vulkan and the command set to 4096.

Also changing the following just reverts them back to defaults, so no hope boosting FPS with these:

r_shadowAtlasTileSize "1024"
r_shadowAtlasHeight "4096"
r_shadowAtlasWidth "4096"

[Gusta]

So I actually used the commands after the game loaded and it boosted my fps by ALOT, by alot I mean jump from 60 to 100fps, no joke. Only problem was that the game was saving the command into config, so it would freeze after loading over again if you turned the game off and on. The workaround was simple, setting the virtual texture size setting to higher than youre used to, saving the settings by turning the game off, and having a .cfg file that you will always exec each time you start the game.

.cfg
vt_pageImageSizeUnique "2048"
vt_pageImageSizeVmtr "2048"
vt_restart

Put into C:\Users\<yourname>\Saved Games\id Software\DOOM\base
Exec in game with this command: exec name.cfg

HAVE FUN!

Desmight: I know this post is old now, but your instructions worked like a charm for me.

I'm running an older Win10 system, ASUS P8P67 Pro motherboard, Zotac GeForce GT730 2GB video card, 32GB RAM.

I just started playing Doom. My frame rates were abysmal prior to this 6-10 fps, unplayable.

After editing the config file and making it read-only, frame rates still low, but at 22-24, it's at least playable now. Not the 60+ fps that others will likely get, but it works for me.

Thank you.

I'm really glad to hear it. Since the date of the first post I've upgraded my GPU, but I'm happy that this fix can still help someone in any way, let's hope it keeps running ok on your machine :)

I hope this doesn't count as necro, but more people need to see this!
My system specs are Gigabyte GTX 770 2GB and i5-4570@3.20GHz.

In the second level when you open the airlock the game started to really stutter and tank fps even on low to medium. With this fix it runs butter smooth at 60. Yeah you have a bit of texture pop in on the weapon and new areas, but that is a small price to pay for silky smooth 60 FPS goodness!
Gonna see how well this holds up, but so far this is amazing. :3

I actually noticed btw. that I don't need to set it to read-only mode. The file doesn't get resetted when I start or restart the game, nor when I enter a new level without read-only.

/UPDATE:
Sitting in level 3 The Foundry where many people reported performance problems. Runs silky smooth at a mix of medium to high settings (shadows to low). I can't say how happy I am about this!

[rawWwRrr]

I had this running on a GTX 570 HD with less than 2gb, so it is possible.

[Taki]

is insane because someone with my same laptop, same cpu and gpu (i7-3720qm quad core, amd 7970m 2gb) to him, run around 50/60fps full hd on open gl, to me run TERRIBLE both open gl and vulkan, less vulkan but still unplayable.

and before i buy it i try the demo and in the demo, was running much much better, with no issue, in opengl.

i tryed your fix, both in config file or as exec in console and is not working, in the beginning when doom load, for some second run a little better, then again run so bad even the menu shutter and the gpu is 100% no matther what, in menu too.

im really disappointed, why the devs dont adress this issue? clearly there is a bug about 2gb gpu cards, who in some cases happen some other no, even with same hardware specs.

[Super Bambaspis]

with the 2GB bug the GPU is generally under utilized. If your having issues and your GPU at 100% load, then it's likely not the same issue. The whole reason the 2GB bug exists is because the game CAN'T use 100% of your GPU. The GPU starts using a cache in virtual VRAM, the GPU's Bus Interface gets hammered, as well as the memory controller, and the GPU spends a lot of time waiting (which explains the lower GPU usage).

I'm not sure why your friend is getting such good FPS with your same GPU, because that GPU is only a little more than 1/2 as powerful as the min spec GPU - and people with the mid spec GPU struggle to get good FPS. Most likely his settings are lower than yours - or he's not reporting his FPS honestly.

Your performance sounds about right for your GPU, but there are some things you can check:

Make sure you aren't forcing AA, or DSR in your GPU driver settings.

Also this game handles v-sync in a bit of a funny way, and will lock your performance at 30fps if you drop below 60fps. Enabling tripple buffering, or disabling v-sync will avoid the issue.

If you ARE suffering from the 2GB VRAM bug, the shadow setting fix is the most reliable thing to do.

from whre you tell my gpu is half the minimum requirement?

http://gpuboss.com/gpus/Radeon-HD-7970M-vs-Radeon-HD-7870

is almost the same as the minimum requirements, and anyway i put all on low and still work bad the same as i put all on high.

i dont know, what i know is in doom insternal stats cpu and gpu are both red, and in hwinfo the cpu are at 50/60% and gpu at 60% in menu and cpu still underutilized in game but gpu 100% use, always, in game.. didint come down not even to 95 or 99%, ALWAYS at 100% even if i look the floor and the fps jump from 30 to 90, even if vsync is active.

anyway even in menu the game shutter and also the mouse move very bad, at 45/50fps, in opengl, with vulkan the menu are fine at 60fps constant, but then when game load i have more fps, but still terrible shutter and is unpleable, both vulkan and opengl...

i also know the demo was working much much better, i play it 2/3 times with different setthings, and was running even in opengl much better, then i buy it and was this mess, who seems to even get wors after last update.

this permormance is not about right for my gpu, is clearly a issue here.

even when i get 60fps stable in some room with no enemy shutter and is something really wrong in how the game render at screen.

and the man i talk about is not the only one, other people with same laptop and similar cpu/gpu play fine, with low setthing.

ah, is the only game who behave like this, i can play bf4 and other demanding games with no issue.

[Taki]

where i can find the fix for the shadows?

I hate to ask, but: Do you know how old your GPU drivers are and how to tell? I'm guessing yes, but I'm just being sure.

Menu performance doesn't matter, I wouldn't focus on that at all.

I did say a little more powerful than 1/2, which is underselling it a little I admit.... the 7870 is ~37% faster in sythetics. Synthetics are a good gauge, considering both GPU's are of the same architechture. Under 2/3 as powerful as the min spec, and that's very significant. Though, in games, it will perform between 45 - 25% slower depending on the game... so it's somewhere between 1/2-3/4 as powerful as the min spec card. It's definately not on par with it though, and it's not close.

The fact that your GPU is pegged at 100% is showing that your GPU is performing the best that it can. There's no way around that, it's your bottleneck. Just make sure that it's not in a low power state... laptops do throttle GPU's to save power in some cases, and do make sure that if you have dual GPU's that it's not dropping back to the weakest one.

Whats your resolution scale setting? If it's higher than 100%, that's your problem.

Again, just double check that you arent overly stressing your GPU with DSR or AA, either in game or in your GPU control panel.


Of course, you can still try the settings fix to see if it helps you. This fix works for most people that have the issue:

While playing:
1) Go to advanced options
2) Turn shadows to Ultra, apply, then exit the menu and play for a few seconds.
3) Go back to advanced options
4) Turn shadows to low, apply
6) Exit the menu and play

No matter what some parts of the game will be bugged whether you do that or not, especially the hell levels.

[Super Bambaspis]

I should link this video. This is before the performance is bugged (Or after applying the fix), and then while the performance is bugged.

how menu performance doest matther if in menu happen same shuttering happen in game so bad affact mouse movement?

also doesnt matther the doom demo i try before to buy doom on steam was working pretty decent?

man you sure the gpu is the issue, even if was the issue there is NO WAY IN HELL, a game can use 100%, always, not even 1 second come down to 99% of gpu utilization, even when i look the walls with vsync active.

not even the most weak gpu have a 100% use always, even in lokkinf to a wall or to floor.

ok thanks i will try it.

belkive me im not stupid, if the game had this performance in the doom demo i didint buy it, but the demo run pretty decent even in opengl. The demo never show issue in game and didint show issue who affect also the menu.

the gpu driver are one of the last beta, anyway also with a older beta i have before same issue.

intel integrated gpu driver are the latest too.

cpu core are unparked, i dont over scale the resolution, are at 100%, anyway even if i put at 70% or less the game still shutter and run as ♥♥♥♥ and gpu is still al 100% fix.

i run win 8.1 64bit, updated, no viruses, no ♥♥♥♥ installed, i take care of my hardware/software.

bf4 run at almos always 60 fps stable at 2560x1080, with custom config even in biggest maps.
