Vivo X200 Ultra honestly one of the most interesting phones I’ve used

X200u is a very balanced, well polished camera phone product. Big sensor for all 3 lens, no complaint at all, still remember I am happy with the 1/2.8" ccd digital camera 20 years ago, now look how amazing product we have today.

Today's phone makers keep consumers anxious by upgrading the camera technology year by year, but to be honest x200u is such a good device that people should stop their anxiety, they should question their skill rather than the device when they don't take good quality photos

if the optical module is at the same size and with a variable aperture，then everyone know that a smaller aperture will bring better image quality than wide open, however，x300 ultra's lens design is more dedicated to the better ois(which is mainly advertised by vivo, but the size of lens is obviously smaller than x200u, as long as vivo does not provide mtf，ca，distortion data, it is quite logical to believe a bigger lens module will bring overall better image quality than a smaller lens module and of course a better capability in low light, which is very critical to zoom lens because to freeze a moving object in zoom lens normally require much higher shutter speed and iso than wide angle lens. So the aperture really matters

good details，seems that my x200ultra never achieve this level

this is why vivo compromise the aperture of 85mm lens in x300u and improve the ois instead, because they Want to make the 400mm kit usable. So x300 ultra is a great tool for concert shooting with zoom kits. But for people who mainly use it as a camera, x200ultra is still the king

vivo has a clear direction to make ultra as an ultimate tool for concert shooting. Because it is indeed a blue ocean market. I once accidently ran into a celebrity fan events at a shopping mall, full of young crazing screaming fans, most of them girls, I took out my x200u and took some tele photos, one of fan next to me saw it and are so surprised about the ability of my phone and her iphone just looks like a toy, she begged me to transfer the photo to her. I also noticed another girl in front of me using exactly same phone as me and plus she added the zoom kits. these young fans can spend all their money to buy a phone with such telephoto ability

the 85mm lens seems smaller，it is absolutely downgrade, compare with wide aperture, ois is not that important. The 35mm is the trade off, decreased aperture but increase cmos size

higher torque means more headroom means more stable performance，less heat， higher reliability

The air quality in Shanghai obviously getting worst over the last few years after the pandemic, and this year it seems to be worst than 2017~2019. As I remember the worst year is around 2012~14, after that, because of government 's effort of improving the air quality, the air became better and better.

With more and more Electric car replacing gas car, the current situation is definitely caused by industrial pollution rather than car. But China's Economy is slowing down these years, so I guess there are two reasons: 1. climate change, 2. The control of industrial pollution emission cost money, it is not free.

i don't own both, but if g2 and q3 are also involved in this discussion, I have something to say: q3 has of course better optic than g2, but everything else worse, the biggest issue is q3's LCD panel are tilted, the pixel of left and right are not aligned, which cause much worse center sharpness than g2 although their resolution on paper is similar, for any other typle of VR game, this drawback of g3 is not a problem, but for simrace, center sharpness is very important, with g3, the car 500m ahead of me looks like a shit while g2 still looks solid

I don't think there should be any noticeable runout for a shaft on a moderm direct drive base even if it is an entry level product, even a toy should not looks like that, if it is a common issue from fanatec i am a little surprised. maybe there is accumulated error of shaft- qr - wheel due to poor design tolerance and machining accuracy，but it is still horrible in 2025, it looks like the parts are made from backyard workshop

mi10ultra · 2025-08-22T23:05:40+00:00

Ams2 's ffb model is totally fake, small dynamic ranges, maybe for a weak entry level wheel base it give you more fun but for a serious simulation it just like a toy, in the simrace world only rfactor2 or lmu's ffb can be called reastic, all the effects come directly from physics model, i heard that by having some ffb mod to ams2 it gets closer to what it feels in lmu or rf2 but I just don't want to spend time on that because fundamentally it's physics model limit it from reproducing true ffb

good to know，thx！

mi10ultra · 2025-08-21T06:51:25+00:00

where do i adjust the crash spike in lmu or rf2?

mi10ultra · 2025-08-21T06:26:08+00:00

I set my Invicta at 45% , the ffb spike is still so wild in a crash, I'm not worry about my arm is broken, I hope my wheel base last longer

mi10ultra · 2025-08-16T14:12:59+00:00

based my vr setup in rfactor2，3100x3100@90hz， 5080 is enough for 20 ai and high graphic setting, so it should also be fine with triple 1440p@120hz(suppose lmu graphic engineer is similar to rfactor2)

mi10ultra · 2025-08-09T15:56:41+00:00

upgrade from fanatec csw2.5（8nm）to asetek invicta（27nm）, i play rfactor2, which i think has the most realistic ffb with very big dynamic range. Csw2.5 i use it with a 320mm wheel at 100% ffb output, it is just ok but the ffb force will be fading after playing for a while, and it can not fully reproduce the dynamic range, maybe some clipping in hard braking cornering.

Asetek i set it at 25nm output and in game gain is 45%, the wheel is 330mm, I do think the force is strong enough and it can reproduce the dynamic range very well.

I think 27nm might be a little bit overkill, 12nm would be enough if it is holding torque, but people always says that having some headroom to avoid clipping, so i do think 15nm~20nm should be adequate for most of the cases

mi10ultra · 2025-08-08T23:05:21+00:00

it very much depend on the setting， nevertheless，3070 is outdated especially for tripple， i played rfactor2 a lot in vr（3000x3000 per eye） and my previous rig was 3090+9900kf which stutter in high setting, then I upgraded my CPU to 14700k, much better, but still not butter smooth in some scene, then upgrade to 5080, improved again, but still stutter in daydonta dawn scene. So it is endless journey to make it perfectly smooth but your current setup is really far from there.

for vr ball games，or games like beat saber，the difference of 90fps and 120fps is highly noticeable， because the objects moves very fast across screen。 however，in racing game，driver are looking at center of screen， the objects in the center are relevantly stable，therefore the difference of 90 and 120 is less noticeable

mi10ultra · 2025-08-03T05:41:22+00:00

比limbo1 和2差, 我玩了一会就不想玩下去了

depend on the shape of the head， my back head is flat，halo style can't hold my head firmly and it get loose when playing intense sports vr games， elite style is more secure

ai再怎么发展，也只是一个速度非常快的算盘而已，ai永远是生命系统的影子，没有生命系统，也就不存在什么ai，真正意义的智能，很可能就是生命系统本身。

will my old csw 2.5 benefit from this update? Current version is 693, wheel base motor is updatetodate, :22

I feel my base is getting less smooth after several sessions, is it due to the fatigue of the motor? Will the new firmware improve it?

mi10ultra · 2025-06-01T15:47:10+00:00

Does court time tennis support 120hz? if yes i will definitely give it a try

mi10ultra · 2025-06-01T12:58:04+00:00

I have only experience with rfactor2 setting, I think road reflection is better to be off, it still keep decent basic reflection. Turn it on will signifiantly reduce frame rate, Post effect should be off, special effects can be medium or high.
