Windows 8.1 users. Run GTA V with Windows 7 Compatibility for a decent perf boost.

Prior: 42FPS avg w/ dips down to 30fps.

After: 52FPS avg w/ dips down to 45fps.


i7 4710HQ @ 3.2GHz | 8GB GTX 980M (equiv to GTX 770 Desktop) | 16GB DDR3 | Win 8.1 Pro 64-bit

Res: 2880x1620
Settings: All Very High | FXAA | 0x MSAA | Depth of Field Enabled | Nvidia PCSS Shadows

If I set post fx to normal my avg fps jumps to 72 (it's a massive perf hit when post fx is at very high or ultra)

Because if you run it at Win7 Compability you run the game at DX10.1 and not DX11.

Windows 7 currently supports up to Direct X 11 and Windows 8.1 supports up to Direct X 11.1. Given that Windows 8.1 generally performs better in every facet over Windows 7, this leads me to believe that little testing was done on 8.1 and the major focus was ensuring that this game worked best on Windows 7. That is pure speculation however and I have no idea as to how or why setting compatibility mode to an older, less optimized OS would make a game like GTA V run better. But it does and Steam's fps tool hasn't failed me yet.

[Lighto]

So should i install 7 or 8.1?

[Marshal Amim Kagori]

8.1

[courage]

If someone thinks, that Windows 8.1 is better than 8, then they are wrong. It was marketing for Microsoft and shops, which are selling OS.

I recommend installing Windows 7 for x64 platform.
I had dual boot and They are same but Windows 8.1 have

Windows 8.1:
+ faster startup(doesn't matter because most of users uses Sleep instead of Shutdown)
+ some miliseconds faster file copying from USB;
+ metro for tablets

BUT Windows 7 is going OVER it:
+ having better 3DMark Vintage score;
+ better GUI;
+ saving eyes(not fusing colors when you are working with multiple Windows, so better for work)
+ much more users is using Windows 7 (exactly Steam users), even Steam owner Gabe - http://www.neowin.net/news/valves-gabe-newell-calls-windows-8-this-giant-sadness
+ start menu(which is back @ Windows 10);
+ clean;
+ better performance for games like Battlefield 3 or Counter-Strike Global Offensive

Guys, u just read, but do not check.
DirectX 11 is same DirectX 11.2 and it's isn't obstacle, they are same. Check Google Images for comparision.

GTA San Andreas was made for Windows 2000.
GTA IV was made for Windows Vista.
GTA V was made for Windows 7.
GTA VI will be made for Windows 10.

[Marshal Amim Kagori]

:lol: What a joke, Windows 8.1 is superior, period. Btw, just reserved my copy of Windows 10 :D

[courage]

Lucian04, i am not joking. I am 100% sure as i tested them in dual boot at 2015 04. May, with latest NVIDIA/i7 drivers.

GTA V uses DX11: http://pcgamingwiki.com/wiki/Grand_Theft_Auto_V

[Marshal Amim Kagori]

For starters you linked me to a general wiki; I'm not going to waste time playing "Where's Waldo" searching for what you want to read.

Where general OS use and software performance is concerned, Windows 8.1 is the clear winner. Especially if you have a UEFI setup with multiple SSD's in Raid 0, Windows 8.1 will always take the cake.

Synthetic Benchmarks do not translate well into actual performance. So they're bullcrap as far as I'm concerned.

Where game performance is concerned, the difference between multiple operating systems on the same DX standard (if the hardware remains the same) should be absolutely negligible (maybe 1-5fps difference) and it is in the case between Windows 7, 8 and 8.1

GTA V is an unexplainable anomaly as to how and why it performs a bit better when run in Windows 7 compatibility mode. I have literally never heard of this happening before or after. Only with GTA V.

The other points you bring up mean nothing as they're moot points. Hate the Tile menu? Windows 8.1 can be set to start at desktop. Hate the lack of a start menu? You can install Classic Shell for free or if you want something more powerful you can get Start 8 for a couple of bucks. Who gives a crap about what Newell says about Windows market share? Windows 8 and 8.1 are backwards compatible was basically everything released in the last 20 years or can be made to be. Same as Windows 7, Windows Vista, Windows XP, etc, etc.

This is 100% true, the only people who disagree are either still on the "hate 8" bandwagon because of the Metro interface, or they are simply hipsters who think it's cool to dislike anything that is new or updated.

I relived this with my Gigabyte P35X V4 (i7 4710 HQ | 16GB DDR 3 | 8GB GTX 980m | 120GBx2 M.2 SSD in Raid 0 | 7200RPM 1TB SATA III HDD | Windows 7 Pro 64-bit). I dealt with Windows 7 for the first three months of ownership, but after already having extensively used Windows 8.1 on other laptops, my work PC and my HTPC, I just couldn't stand Windows 7 anymore. Reinstalled Windows 8.1 on my laptop and its been an absolute dream, especially its search and boot/wake up performance on Raid 0 SSD's. Everything I do is practically instant.

[Marshal Amim Kagori]

Hololens seems like a joke for personal use, but I could definitely see some very interesting commercial applications for it.

[chebonaparte]

lol weird.

i can run GTAV fine on 8.1 but GTA online is awful lag

Lucian04 you didn't tested both OS'es, because you do not agree with me.
Even most developers knows that there is no real reason for 8.1 using, except Windows Store (practically dead, if we compare it with Mac App Store) and it's Metro.

If we talk about benchmarks / performance, then Why 7 is better? Why 3DMarkVintage gives much more Score for Windows 7?

DX11 vs DX 11.2, is like M1 Abrams vs M1 Abrams. No differences.
Microsoft/NVIDIA is not comparing 11.2 version to 12, because it's having same performance, as 11.

So, there is no reason for using 8.1(except for Tablet), it's more brain problem.
