XCOM 2 memory shock

[Kaapstad]

I saw an article on another forum where they tested performance on a Fury X and GTX 980 Ti and I noticed the performance on my TitanX was much better maxed @2160p

Below is the reason why I think

Check out the memory usage.

Memory filled may not be the same as memory needed for a certain level of performance. A general principle in many areas of software is that you don't flush the cache until you need it for something else. But that doesn't mean what's in the cache is in use. For example, there was an article on Tweaktown comparing Fury X with Titan X and despite the huge discrepancy in memory, they were close to equal in many areas and the Fury X even took the lead in a couple of places. But if the memory usage on the TitanX had been measured, there's a good chance that double the 4GB that the FuryX was cheerfully running on would be filled on the TitanX.

You would need to test the VRAM usage on the other cards. Just because it uses 10 of 12 on a Titan X does not mean it tries to use 10 on a 4/6GB card.

It is an interesting talking point given the performance issues the game has though. Needs more investigation.

Check the performance of the Fury X and GTX 980 Ti in the link in the OP.

I am getting nearly 3x the fps (on a single TitanX) the GTX 980 Ti gets at maximum settings.

I would say that neither the Fury X or GTX 980 Ti have enough memory to max the game.

SLI or CF support on the GTX 980 Ti or Fury X with max settings will probably do very little and if anything will make things worse.

Cheers and might well give this a look at the weekend

The game is well worth a look. I will be playing it a lot for the next few months.

It is also very playable on max settings @2160p with a single TitanX.

All credit to NVidia for having the foresight to equip the TX with 12gb of VRAM, games like XCOM 2 will become very commonplace in the next 12 months and people need to accept that is the way things are going.

The previous XCOM game got good SLI support about a month after launch and hopefully the same will happen with XCOM 2.

Anyone thinking about buying a next gen card should hold off until they are available with at least 12gb or 16gb of VRAM. Anyone buying next gen cards with only 8gb will be making a big mistake.

Although I tend to agree with you, I am curious if we're not hanging up too much on this single game in this respect?

There are a number of games out now that can breach 8gb @2160p, Watch Dogs and GTA V are a couple that spring to mind.

Another thing that often gets said is you can not see the effect of 8XMSAA @2160p but the truth is in some games you can.

Its using that because it can but i have no doubt something like this really needs more than 4GB, which i think is what you are saying?

I can well believe it, Star Citizen already needs 3.8GB at 1080P and my GTX 970 knows it!

This in Crusader, what is commonly known as the "Baby PU" (Public Universe) IE its Alpha and tiny compared to what it will grow into.

We are going to start needing those 8GB cards in the midrange.

Using the settings I was using a GTX 980 Ti or Fury X can not run as they are memory limited and the fps tank.

Check out the link to OC3D in the OP for the 980 Ti and Fury X results @2160p maxed.

Using a TitanX I get 3x the fps that they got with the 980 Ti as the TX is not limited by memory.

This is one game that definitely needs loads of memory. If it's predecessor is anything to go by we should get SLI support in the next month or so.

Anyway I have to go as there is a bunch of aliens that need some careers advice at the point of a plasma cannon.
